Numeric integration is not documented

I looked in both of these pages and I can't find any mention of the fact that SymPy can compute integrals numerically: https://docs.sympy.org/latest/modules/integrals/integrals.html https://docs.sympy.org/latest/tutorial/calculus.html#integrals SymPy's numeric integration (from mpmath) is...

roots_binomial should use exponentials instead of trig

2

While investigating gh-21907 I realised that the cause of the problem there is that roots returns complicated trig expressions: ```python In [2]: roots(x**7 + 1, x) Out[2]: ⎧ ⎛π⎞ ⎛π⎞...

The use of `nsimplify` here leads to incorrect results: https://github.com/sympy/sympy/blob/e2cadc140cc969fea038240a39961a66a2f3dd6d/sympy/functions/elementary/exponential.py#L1047-L1048 This series should just be all zero terms: ```python In [3]: g1 = 2*acosh(1+2*z/3)-acosh(S(5)/3-S(8)/3/(z+4)) In [4]: g3 = 2*log(sqrt((z+4)/3)*(sqrt(z+3)+sqrt(z))**2/(2*sqrt(z+3)+sqrt(z))) In...
