此次网课代修的内容是edx在线课堂的Pre University calculus(微积分)代修，一共7week，我们最终为客户顺利保A。

　　

欢迎使用功能-第1部分

　　本周的主题是函数。首先，我们将以NUNA太阳能汽车为例来研究函数在数学建模中的作用。您将学习函数定义，以及域、范围和连续性等属性。本周我们将研究多项式函数、有理函数和幂函数的性质。你将学习这些函数的计算规则，并且实践很多!

　　这周我们结束了大学关于泰勒多项式的预览，给你一个你在大学可能遇到的数学趣味。

　　本周的学生生活主题是计划。我们帮助你，鼓励你为这门课程做计划!

　　Welcome to Functions - part 1

　　This week the topic is Functions. First we willlook at the role of functions in mathematicalmodeling using the Nuna solar car as anexample. You will learn the definition of afunction, as well as properties like domain,range and continuity. This week we will lookat the properties of polynomial functions,rational functions and power functions. Youwill learn the rules of calculation for thesefunctions and practice a lot!

　　We finish this week with a university previewon Taylor polynomials to give you a flavorefthe mathematics you might encounter at university.

　　The student life topic of this week is planning. We help you and encourage you tomake a planning for this course!

　　

欢迎使用功能-第2部分

　　本周我们将继续研究职能。我们将从

　　三角函数，如正弦函数、余弦函数和切线函数及其计算规则，然后是练习，让你有机会应用这些规则

　　你自己。既然你知道不同类型的基本函数，你就学会了

　　编写它们，以及缩略语和翻译的操作。然后，您将使用储蓄账户作为示例来学习关于正向函数的知识。“定义对数需要逆函数的概念。

　　本周的大学预览是傅里叶级数，用于声学、光学和信号处理。

　　本周的学生生活主题是“介绍活动”。这些活动给了你很多机会去认识朋友，找到你喜欢的活动。

　　Welcome to Functions - part 2

　　This week we will continue working onFunctions. We will start by looking at

　　trigonometric functions like the sine, cosineand tangent and their rules of calculations,followed by exercises to give youthe opportunity to apply these rules

　　yourself. Now that you know different typesof elementary function you learn how to

　　compose them and the operations of scalingand translation. Then you will learn aboutexponential functions using a savingsaccount as an example.' The concept ofinverse function will be needed to definelogarithms.

　　The university preview of this week is aboutFourier series, used for example in acoustics,optics and signal processing.

　　The student life topic of this week is"introduction activities". These activities'offer you plenty of opportunities to makenew friends and find activities you like!
