Hello,
Do we have any formula for
Integral of
and also
In that case use post #6. It is the best way to do it.
There is a LaTeX tutorial here.
I don't know what you mean by "sth', but if you need to write your indefinite integral in terms of sines and cosines, use integration by parts twice.
Otherwise, if you want a quick way to perform the integration, first convert the hyperbolic functions to their exponential forms.
