Warm-up Graph two full periods for each. Label each axis.
Objective • Evaluate inverse trig functions.
Review Inverse Functions For a function to have an inverse function it must pass the HLT. What can we do to make them have an inverse function?
Graph the inverse sine function Restrict the domain Switch x and y to graph inverse
Graph the inverse cosine function Restrict the domain Switch x and y to graph inverse
Graph the inverse tangent function Restrict the domain Switch x and y to graph inverse
Practice • Evaluate without using a calculator
