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
:
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.
