#14764 closed defect (fixed)

Let Mathematica free integration work with definite integrals

Description

See ​this ask.sagemath question. Apparently 

sage: integrate(x^2,x,algorithm='mathematica_free')
1/3*x^3
sage: integrate(x^2,x,0,1,algorithm='mathematica_free')
1/3*x^3

so that would be useful to fix. Since it currently returns an indefinite integral when we ask for a definite one, I'll classify this as a defect.

  • Status changed from new to needs_review

This seems fixed in recent Sage versions. IN 9.2.beta0: 

sage: integrate(x^2,x,0,1,algorithm='mathematica_free')
1/3
sage: integrate(sin(x),x,0,pi,algorithm='mathematica_free')
2
sage: integrate(sqrt(x),x,0,1,algorithm='mathematica_free')
2/3
sage: integrate(sqrt(x),x)
2/3*x^(3/2)

Needs doctest if these aren't already tested (which they may be).

Replying to kcrisman:

Right. Putting this to needs_work.

Added relevant doctests to src/sage/symbolics/integratin/external.py, which pass for me.
