Answer 1

I have a Casio 991MS.
there is an inbuilt integration/ differentiation button.
You enter the parameters as the mentioned in the manual.
In mine, I enter it like this:

Differentiation:
d/dx(f(x),n)
f(x) is the function to be differentiated. n is the corresponding value of the x coordinate where the function will be differentiated.

Integration:
Integration(f(x),l,u)
l=lower limit
u=upper limit
