2. dy/dx

This is a calculus application. dy/dx gives a numerical approximation of the first derivative at the indicated point. You can use trace to get to the x-value or you can enter a value of x.

Example: Find the numerical derivative at x=1 and x=-1.

Enter the function.	Graph with ZDECM.	dy/dx:
Enter x=-1.	dy/dx at x=-1	dy/dx at x=1
