Hi!
I have problems solving integral with this function in Mathematica:
(Sin[x])^5
---------------
(Cos[x])^(11/4)
Mathematica format:
\!\(\[Integral]\(Sin[x]\^5\/\@\(Cos[x]\^11\)\%4\) \[DifferentialD]x\)
Mathematica produces a complex solution using Hypergeometric function which is not what I want.
With Derive and manual integration (cos(x)=t) I get this(in Mathematica format):
\!\(4\/\(7\ Cos[t]\^\(7/4\)\) +
8 Cos[\ t]\^\(1/4\) - \(4\ Cos[t]\^\(9/4\)\)\/9\)
Why do I get complex solution instead of this much simpler result? Do I have to specify correct domain?
