Hi,

I found a bug where a definite integral is calculated wrong.
WolframAlpha result for comparison.

Code:
integrate(sqrt(2-2*cos(x)),x,0,2*pi)

Also if I type show() instead of print() SageMathCell won't show anything.
Also the indefinite integral does not simplify well.

Sry for the double posting.
My first post just didn't show up and I thought something went wrong.
