To find

derivatives in the

Function apiet’s

Symboiic view

To find the derivative of the function in the Function apiet’s

Symbolic view, you define two functions and define the

second function as a derivative of the first function. For

example, to differentiate sin(v' ) + 2cos.v:

1. Access the Function apiet’s Symbolic view and define

FI.

You could also just define
