@Eric Wofsey but does it obey the above formulas?

comment Solutions of sixth order polynomial equations
In what form do u want the solution - series, special functions, limit or anything else? Some computer algebra systems already have root of a polynomial as a built-in function.

comment Why is $\lim_{(x,y)\to(0,0)}\frac yx \ne 0$?
It is discontinuous at (0,0).

comment Why is $\lim_{(x,y)\to(0,0)}\frac yx \ne 0$?
Depending on your definition of the limit with two variables, it can be 0.

comment Can the Riemann Zeta derivative be expressed in terms of Riemann Zeta?
The problem with your addition part is also that polygamma is not defined for non-integer indexes as well.

comment Concerning Hurwitz Zeta function, how to prove the following identity?
I've got the following: $$\int_0^{\infty } \frac{1}{4} (\coth (\pi t)-1) \left(a^2+t^2\right)^{-\frac{s}{2}} \left(2 \tan ^{-1}\left(\frac{t}{a}\right) \cos \left(s \tan ^{-1}\left(\frac{t}{a}\right)\right)-\log \left(a^2+t^2\right) \sin \left(s \tan ^{-1}\left(\frac{t}{a}\right)\right)\right) \, dt$$ using Mathematica.

After I differentiate the expression under the integral I get something different. How do you get this?

Great! Is there a way to obtain a more general formula, that is with a variable instead of 0?
