I'm trying to use sage for documentation purposes, and I'm looking for a way to do some of the following.
Enter an equation
f(x) = 2x
Input f(2) or something close
and get back f(2) = 4 instead of just 4.
I'm also looking for a way to input
f(x) = 2x^2
Input diff(f(x),x), or an equivalent command and get
f'(x) = 4x or d(f(x)/dx = 4x.
And an icing on the cake would being able to input integrate(f(x)dx)
and return ∫f(x)dx => 4x + 15 + c
Bassically, if there is a way to the output more verbose, I'd love to know how.
I just started using Sage and I love it, thank you!

Thank you so much for the response @paulmasson

Your word "typesetting" was new to me and helped me find some other posts.
This This seems to be my exact question:

This question:
This one seemed to answer my question, but I don't know if I'm supposed to do this.
https://ask.sagemath.org/question/30975/present-sage-output-as-normal-mathematics/this.
It gave me the idea of using f = function('f',x) == 2*x
I have no clue what function() is, but I'm working on it.
I have no idea how or why this is different from f(x) = 2*x, but it's pretty cool because now diff(f,x) evaulates to d(f(x)/dy = 2
However, it doesn't do diff(f) so well when there are two variables like f(x,y) = x^2 + y^2 .
I also really enjoyed this one:
