RE: Difference Quotient Calculation
One easy way might be to define a function e.g. F1(X) in function.
Change to CAS and type the difference quotient:

(F1(x+DELTA) + F1(x)) / DELTA

To see it a little bit better:

EXPAND(ANS)

Now you can get the derivative by applying the limes. You can double check it with the derivative (see screenshot).
