I am confused about which function to use for hypergeometric calculations - [this](https://functions.wolfram.com/ElementaryFunctions/Cos/26/03/05/0001/) or [this](https://functions.wolfram.com/ElementaryFunctions/Cos/26/01/01/0001/). Can you please help me choose the right one?

Hey there! I'm having a bit of trouble with `_rewrite_single(trigo(x), x)` and was hoping you could help. I'm getting a value for `cos` and `sin`, but not for `sec`, `cot`,...

there is no formula of tan, cot on Meijer G on [wolfram](https://functions.wolfram.com/ElementaryFunctions/Tan/26/). shall I use sin/cos? I thing It will appear as incorrect. P.S. I can get a return of...

sorry for spamming the message. I didn't understand, that I should return `Integral(tan(x), x)` when using the method ` tan(x).rewrite(hyper)` ?

I believe we simply need to set the 'is_commutative' parameter to 'True'. Why has this PR not yet been merged?

Symbolic expressions often involve complex data structures, and memory usage may depend on factors such as the expression size, the number of variables, the presence of shared subexpressions, and any...

@sympy-bot Assigned me this issue

* The definition of [Sympy](https://docs.sympy.org/latest/modules/functions/special.html#sympy.functions.special.polynomials.assoc_legendre) and [mpmath](https://mpmath.org/doc/current/functions/orthogonal.html#legenp) are mostly likely same. * The different name use in * scipy :- scipy.special.legendre * numpy:- numpy.polynomial.legendre.Legendre

Dear @oscarbenjamin, please accept my sincere apologies for my previous behaviour. In the future, I will ensure that my messages are clear, concise, and respectful at all times. I understand...

I tried to add a test case with a pull request, but I keep getting merge conflicts. I even pulled master into my branch, but I still got merge conflicts....
