Hi everyone,
I have an equation that contains the derivative of the Bessel Function of the first kind. I need to evaluate J_{n}'(x) for small values of x (x<<1). I know that J_{n}(x) is (x)^{n}/(2^{n}*n!). What is it for the derivative?

Hi !
You can derivate the series expansion or alternatively expand the formal derivative. Both methods leads to the same result.
