Week 4 Trigonometric Functions of Any Angle

Week 4

Acute angles in standard position are all in the first quadrant, and all of their trigonometric functions exist and are positive in value. This is not necessarily true of angles in general. Some of the six trigonometric functions of quadrantal angles are undefined, and some of the six trigonometric functions have negative values, depending on the size of the angle. Angles in standard position have their terminal side in or between one of the four quadrants. 




When trying to find the angles you have to use the inverse of Sine Cosine and Tangent
This week was a little harder than week 3 the concept was harder to grasp with Khan Academy's videos I can gain a full understanding of this Concept overtime.
