Whether you are starting your own business or supplementing your understanding of accounting, this business course will help you understand accounting basics and give you meaningful financial tools to understand business.
Understanding the four basic financial statements, Income Statement, Balance Sheet, Statement of Retained Earnings, and Statement of Cash Flows, is key to evaluating companies for your investment decisions. But this business course goes beyond just understanding these financial statements. Business Accounting Basics takes you through the building blocks and accounting cycles that create each statement. In addition, this course will give you the basic tools to project profitability and break your costs down to help analyze any company.
This course is built to fit the needs of everyone, including those who have a 401k, other retirement plans or want to invest in different companies.
Virtually all managerial and leadership positions in the digital economy increasingly rely on data-driven decision making. Recent studies have shown companies who adopt “Data-Driven Decision Management” achieve significant productivity gains over other firms.
Having a solid grasp of the end-to-end process of making effective decisions with data will give you an edge, both in performing such analyses yourself, as well as in effectively managing teams of business analysts and data scientists.
In this course, part of both the Digital Leadership and Digital Product Management MicroMasters programs, you will learn the tools and techniques to become a data-driven or “evidence-based” manager.
You will learn the process of reframing a business question as a data question, reasoning about what data might be of assistance and how to obtain it, integrating and cleaning the data, performing the analysis, deriving and communicating insights from the analysis, and building the managerial culture to operate in this way and create competitive advantages from enterprise data.
This course is unique in the sense that it aims squarely at the needs of a manager in an analytically focused enterprise by providing both a hands-on introduction to the concepts, methods and processes of business analytics as well as an introduction to the use of analytics as the basis for creating a competitive advantage.
This course is about modeling and how computer models can support managerial decision making. A model is a simplified representation of a real situation and modeling is the process of developing, analyzing and interpreting a model in order to help make better decisions. Models can be invaluable tools in managing and understanding the complexity and risk inherent in many business problems. As a result, models have become an increasingly important part of business at all levels from daily operations to strategic decision making.
This course will help learners become intelligent users and consumers of these models. To this end, we will cover the basic elements of modeling – how to formulate a model and how to use and interpret the information a model produces. The course emphasizes “learning by doing” so that students will be expected to formulate, solve, and interpret a number of different optimization and simulation models using Excel spreadsheets. An important theme in the course is to understand the appropriate use of models in business and the potential pitfalls from using models incorrectly or inappropriately.
The course has two distinct parts:
- The first half of the course we will cover supervised learning techniques for regression and classification. In this framework, we possess an output or response that we wish to predict based on a set of inputs. We will discuss several fundamental methods for performing this task and algorithms for their optimization. Our approach will be more practically motivated, meaning we will fully develop a mathematical understanding of the respective algorithms, but we will only briefly touch on abstract learning theory.
- In the second half, we shift to unsupervised learning techniques. In these problems the end goal less clear-cut than predicting an output based on a corresponding input. We will cover three fundamental problems of unsupervised learning: data clustering, matrix factorization, and sequential models for order-dependent data. Some applications of these models include object recommendation and topic modeling.
In the modern workplace, it’s crucial to know how to analyze, synthesize, and tell stories with data. This self-paced career development course will help you learn how to use a spreadsheet application (like Microsoft Excel) as a powerful analytical and communication tool. You will perform real-world market and financial analyses and practice presenting your findings visually for maximum impact. By the end of the course, you will be able to make data-driven decisions that help your organization grow and prosper.
This is the fourth course in Fullbridge’s four-part Career Development XSeries, designed to prepare you to succeed in the modern workplace.

这门课是从头开始学C++吗?
不是。本课程假定你已经学过C语言，只讲授C++中面向对象和泛型的部分。
C语言不够用吗?为什么还要学C++?
因为C++比C语言更加适合用来编写需要多人协作的大型程序。
学习面向对象编程，我为什么不去学Java，要学C++呢？
C++程序运行效率比Java高，因此需要讲究速度的大型程序，比如3D游戏，C++比Java更适合。另外，C++可以编写任何程序，比如设备驱动程序，而Java很难用于编写贴近硬件底层的程序。此外，学习C++，相比于学习Java，对计算机的工作原理会理解得更加深刻一些。另外，许多IT大公司面试时，常会问关于C++的问题。
我是学生，似乎没什么机会些大程序，那如何能体会C++的优势呢？
本课程由一个足够大的作业《魔兽世界》，可以让你领略C++的明显好处。
Las estructuras están implicadas en nuestras vidas: las plantas, los animales, casi todo lo que fabrica el ser humano, incluso nuestro propio cuerpo, deben soportar una serie de fuerzas sin romperse, y por lo tanto prácticamente cualquier elemento de nuestro entorno es una estructura de una clase u otra.
No cabe duda de que entender cómo se comportan las estructuras es fundamental para entender el mundo que nos rodea, para comprender la naturaleza y para juzgar mejor los progresos que ha hecho la humanidad a lo largo de la historia. Sin embargo, los ingenieros hemos fallado una y otra vez cuando hemos intentado explicar esta materia de forma que los no entendidos puedan entender su importancia.
Este curso pretende saltar esa brecha existente entre los expertos en cálculo de estructuras y los profanos utilizando un lenguaje asequible, empleando ejemplos históricos y proponiendo ensayos sencillos que pueden hacerse en casa. El curso abordará no sólo el problema de por qué los edificios y los puentes se caen sino también otras muchas cuestiones. ¿Por qué las ventanas de los aviones son redondas? ¿Por qué los gusanos tienen esa forma? ¿Por qué los murciélagos pueden volar dentro de un rosal sin rasgarse las alas? ¿Cómo funcionan las arterias? ¿Por qué las catedrales góticas pueden ser tan esbeltas? ¿Por qué hay construcciones romanas que siguen en pie 2000 años después? ¿Qué podemos aprender sobre los constructores de las diferentes estructuras que nos han legado nuestros antepasados?
Muchos contenidos de este curso pueden ser útiles para médicos, biólogos, artistas, historiadores y arqueólogos.
Podemos afirmar sin temor a equivocarnos que un buen curso de Cálculo amplía la visión del estudiante en su campo y en su área de estudio, que no pertenece necesariamente al área de física o matemática, por ejemplo en fisiología para estudiantes de medicina.
El Cálculo Diferencial es el lenguaje en el que algunas leyes de la naturaleza se expresan, por ejemplo: nos permite describir el movimiento y el cálculo de trayectorias en dinámica, nos ayuda a resolver problemas de áreas y volúmenes, a resolver problemas extremales en campos como economía y matemática financiera.
En este curso se presentan los conceptos y demostraciones con extrema precisión y cuidado; se hace énfasis en los fundamentos del Cálculo para que lo que se enseña quede fundamentado y claramente explicado.
Se estudia el cálculo diferencial de funciones de variable real, por lo tanto, se parte de una estructura algebraica de los números reales, Se utilizan conceptos puramente métricos, se introduce el concepto de distancia para explicar que nos vamos acercando a algo, es decir, se define la estructura del espacio métrico que da paso al primer tema sucesiones de números reales continúa con sucesiones convergentes, límite funcional, continuidad y la derivada de una función hasta llegar a problemas de aplicación.
Este curso está en modalidad “self-paced”, es decir, “a tu propio ritmo de aprendizaje”. ¿Qué significa esto? Que puedes empezar el curso cuando quieras y seguirlo a tu ritmo ya que no hay fecha prevista de cierre o apertura de lecciones, no sigue un calendario establecido; los trabajos y exámenes no tienen fecha de inicio o entrega, puedes enviarlos en cualquier momento antes de la fecha de finalización del curso.
Esperamos que este curso de Cálculo Diferencial logre cambiar la percepción de los estudiantes en cuanto a su aplicación e importancia.
How does the final velocity on a zip line change when the starting point is raised or lowered by a matter of centimeters? What is the accuracy of a GPS position measurement? How fast should an airplane travel to minimize fuel consumption? The answers to all of these questions involve the derivative.
But what is the derivative? You will learn its mathematical notation, physical meaning, geometric interpretation, and be able to move fluently between these representations of the derivative. You will discover how to differentiate any function you can think up, and develop a powerful intuition to be able to sketch the graph of many functions. You will make linear and quadratic approximations of functions to simplify computations and gain intuition for system behavior. You will learn to maximize and minimize functions to optimize properties like cost, efficiency, energy, and power.

How long should the handle of your spoon be so that your fingers do not burn while mixing chocolate fondue? Can you find a shape that has finite volume, but infinite surface area? How does the weight of the rider change the trajectory of a zip line ride? These and many other questions can be answered by harnessing the power of the integral.
But what is an integral? You will learn to interpret it geometrically as an area under a graph, and discover its connection to the derivative. You will encounter functions that you cannot integrate without a computer and develop a big bag of tricks to attack the functions that you can integrate by hand. The integral is vital in engineering design, scientific analysis, probability and statistics. You will use integrals to find centers of mass, the stress on a beam during construction, the power exerted by a motor, and the distance traveled by a rocket.

How did Newton describe the orbits of the planets? To do this, he created calculus. But he used a different coordinate system more appropriate for planetary motion. We will learn to shift our perspective to do calculus with parameterized curves and polar coordinates. And then we will dive deep into exploring the infinite to gain a deeper understanding and powerful descriptions of functions.
How does a computer make accurate computations? Absolute precision does not exist in the real world, and computers cannot handle infinitesimals or infinity. Fortunately, just as we approximate numbers using the decimal system, we can approximate functions using series of much simpler functions. These approximations provide a powerful framework for scientific computing and still give highly accurate results. They allow us to solve all sorts of engineering problems based on models of our world represented in the language of calculus.

In this course, we go beyond the calculus textbook, working with practitioners in social, life and physical sciences to understand how calculus and mathematical models play a role in their work.
Through a series of case studies, you’ll learn:
- How standardized test makers use functions to analyze the difficulty of test questions;
- How economists model interaction of price and demand using rates of change, in a historical case of subway ridership;
- How an x-ray is different from a CT-scan, and what this has to do with integrals;
- How biologists use differential equation models to predict when populations will experience dramatic changes, such as extinction or outbreaks;
- How the Lotka-Volterra predator-prey model was created to answer a biological puzzle;
- How statisticians use functions to model data, like income distributions, and how integrals measure chance;
- How Einstein’s Energy Equation, E=mc2 is an approximation to a more complicated equation.
With real practitioners as your guide, you’ll explore these situations in a hands-on way: looking at data and graphs, writing equations, doing calculus computations, and making educated guesses and predictions.
This course provides a unique supplement to a course in single-variable calculus. Key topics include application of derivatives, integrals and differential equations, mathematical models and parameters.
This course is for anyone who has completed or is currently taking a single-variable calculus course (differential and integral), at the high school (AP or IB) or college/university level. You will need to be familiar with the basics of derivatives, integrals, and differential equations, as well as functions involving polynomials, exponentials, and logarithms.
This is a course to learn applications of calculus to other fields, and NOT a course to learn the basics of calculus. Whether you’re a student who has just finished an introductory Calculus course or a teacher looking for more authentic examples for your classroom, there is something for you to learn here, and we hope you’ll join us!
