The indefinite integral of (4/x^5)*cos((1/x^4)-6) is returned unevaluated while for the simpler case of (4/x^5)*cos(1/x^4) it is evaluated without issues. Image attached to demonstrate what I mean.
I tried it as well with the same results.
The CAS-systems of TI (both nspire and ti 89 titanium) and casio (PC Software of Classpad II) solve both integrals without any problems.
Hi, if you press "simplify", the integral is solved.

Now, that's funny. Thanks!
