Attempting to simplify some straightforward expressions involving exponentials of noncommutative or matrix symbols produces wrong results or TypeErrors in the following sample code:
```

```
from sympy import *
x = Symbol('x')
solveset(sin(x) < cos(x), x, S.Reals)
```
returns a non-periodic solution `Union(Interval.Ropen(0, pi/4), Interval.Lopen(5*pi/4, 2*pi))`

Other constants give more or less specific help but

**Description of the desired feature**
Given that our Restructured Text documentation fully support mathematics, it would be nice to try to use it when we do math. If I cd into the doc source dire…

```python
from sympy import pprint, symbols, Integral, sin, pi
x = symbols('x')
Integral(abs(sin(x)), (x, 0, 7 * pi)).doit()

Result is 2, but correct result is 14.

This ticket is devoted to improve spherical harmonics and make them function properly. That entails treating special cases more efficiently and adding a bunch of doctests for checking correctness.

Define the lognormal density starting from the normal:

var("mu", domain="real")
var("y, m, s, sigma", domain="positive")
dnorm(x, mu, sigma) = e^(-(x-mu)^2/(2*sigma^2))/(sigma*sqrt(2*pi))
