To find derivatives in the Function aplet’s Symbolic view

To find the derivative of the function in the Function aplet’s Symbolic view, you define two functions and define the second function as a derivative of the first function. For example, to differentiate sin (x2) + 2 cosx :

1.Access the Function aplet’s Symbolic view and define F1.

2

2.Define F2(X) as the derivative of F(1).

F1

3.Select F2(X) and evaluate it.
