I have this equation:
integrate(exp(-x**2), (x, c, -c))=1/2
which should look like this:
How can I find a solution for c, for example using a library such as sympy?

This post is too general for stackoverflow, you can only ask specific coding questions. I suggest, you read about [sympy](https://docs.sympy.org/latest/index.html) – user8408080 Dec 29 '19 at 12:11

Take a look at https://docs.sympy.org/latest/modules/integrals/integrals.html – JohanC Dec 29 '19 at 12:49

With Sympy you can do the following:
from sympy import *
from sympy.abc import x, c
sol = solve(Eq(integrate(exp(-x**2), (x,c,-c)), S(1)/2))
print("symbolic solution:", sol)
print("numeric solution:", [s.evalf() for s in sol])
Output:
symbolic solution: [erfinv(-1/(2*sqrt(pi)))]
numeric solution: [-0.255449286541000]

Does this answer your question? Or were you looking for some other approach? – JohanC Dec 29 '19 at 21:59
