Investigating Derivatives of Sinusoidal Functions with GeoGebra
Channel: Blackboard Bold
Date: 2017-05-20

We'll use GeoGebra to graph the function f(x) = -sin x and then create a table of values, and plot points, to graphically determine what the derivative of the function would look like.

In this way, you can investigate derivatives of trig functions (or any function, really) graphically even if you're struggling with the algebraic concepts behind these derivatives.

This tutorial assumes you're already familiar with the concept of the derivative as the slope of a tangent line. It does not assume much GeoGebra knowledge beyond how to access the app in the first place.
