MATSEC AM Pure Mathematics Complete Prep Course — Lesson 46: Graphs and inverse trigonometric functions

This lesson sketches the six trigonometric graphs from memory, covering the periods, zeros and asymptotes of sine, cosine, tangent, secant, cosecant and cotangent. It then explains why sine, cosine and tangent must be restricted to be one to one, states the domain and range of arcsine, arccosine and arctangent, and derives each inverse graph by reflection in the line y equals x, including the arcsine of sine trap.
