Antiderivative

[Sophiesmark]

Im having trouble with this antiderivative
S 1/4 arctan x/4 + C

I know that Dx cot x = -csc^2 x, but Im not sure how to work this problem with the fractions.
Any help

Please reply using grouping symbols for clarification. What you have posted could mean:

. . . . .\(\displaystyle \Large{\int\mbox{ }{\frac{1}{\left(\frac{4\arctan{(x)}}{4\mbox{ }+\mbox{ }C}\right)}\mbox{ }dx}}\)

...but I suspect this isn't what you meant.

Thank you.

P.S. It is usually the antiderivative that has a constant "C", not the integral. Are you sure that belongs in there?

Ok, it should read:
S (1/4) arctan (x/4)
