Trigonometry for Electrical Engineering

This course takes you from the fundamentals of trigonometry to the more sophisticated requirements in electrical engineering. As you work and study 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, phases (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 those that may have been long since forgotten.

The student will begin by 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, and double & half-angle formulas. Lastly, the student will look at Trig Functions in the Time Domain

Here is gathered what I believe are the most significant trigonometric items.
