This PowerPoint™ presentation lesson about the derivative of inverse trig function functions has 5 examples (each with a You-Try) and 10 homework problems that can be given to your calculus students as a worksheet or as a self-grading google form. The lesson begins with the derivation of the derivatives of inverse sine, cosine, and tangent only. Inverse cotangent is used in the lesson, but inverse secant and cosecant are not. Example #1 is a derivative at a point, example #2 uses the limit defin
