Integral NA in home, CAS
I can't get int (sqrt (1+x^(-2/3)) from -1 to 1 in CAS, and surpringly, home, no matter how I enter the function. In home, I get invalid input. In CAS, I get a complex number result. It's magnitude does not agree with the true answer of 2(2*sqrt(2) - 1) in the case of nSpire, ~3.657 on Classpad 400.

Is this doable on the Prime?
