Trivial integral substitution quirk
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.

RE: Trivial integral substitution quirk
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. |

RE: Trivial integral substitution quirk
Hi, if you press "simplify", the integral is solved.

RE: Trivial integral substitution quirk
I made a fix in giac source code (https://github.com/geogebra/giac/commit/...975563e66d) ... but I have no idea when it will be available on the Prime.
