**课程名称：** **面向电气工程的三角学** **课程概述：** 本课程将带您从三角学的基础知识，深入到电气工程领域对三角学更高级的应用。在学习电气工程的过程中，您将遇到大量基于三角学的证明和方程。例如，在学习交流电、电压和阻抗计算时，会使用相量（矢量），并在数学上进行组合，这会涉及到三角函数和恒等式的应用。进一步探索复功率的计算同样需要掌握三角函数和恒等式。 在本课程中，您将重新学习或初次接触这些重要的三角学概念。课程将从点、线、角、相交线、平行线和三角形的定义开始。随后，您将学习工程领域最基本、最常用的定理之一，如“勾股定理”。在了解了特殊三角形及其边长比率后，您将学习几种最常用的三角函数，包括涉及正切函数的部分。最后，您将通过单位圆学习多个重要的三角函数恒等式，如和差角公式、积化和差公式、余函数恒等式、倍角与半角公式。课程最后部分将探讨时域中的三角函数。 本课程汇集了作者认为最为重要的三角学知识点。 **目录：** 无
This course takes you from the fundamentals of trigonometry to the more sophisticated requirements in electrical engineering. As you work and study in electrical engineering you are going to run into proofs and equations that are based on trigonometry. A good example of this is when studying AC current, voltage and impedance calculations, phasors (vectors) are used and combined mathematically lending themselves to several needs to rely on trig functions and identities. Further adventures into complex power will also require a knowledge of trig functions and identities. As a student of this course, you will be introduced to these or at least re-introduced to these that may have been long since forgotten. The student will begin at defining Point Lines & Angles, Intersecting & Parallel Lines and Triangles. This will lead to one of the most fundamental and used theorems in engineering, such as "The Pythagorean Theorem". After a look at Unique Triangles and the Ratios of their sides, the student will go on to learn several of the most used Trig functions including those involving Tangents. Next, the Unit Circle will be defined as it leads to several Trig Identities; Sum to/from/product co-functions, double & half-angle formulas. Lastly, the student will look at Trig Functions in the Time DomainHere is gathered what I believe are the most significant trigonometric items.
