# How to use algorithm='mathematica free' to calculate definite integral?

Is it possible to use algorithm='mathematica free' to calculate definite integral ?

```
integrate(x^2,x,algorithm='mathematica_free')
```

Output:

```
1/3*x^3
```

and

```
integrate(x^2,x,0,1,algorithm='mathematica_free')
```

Output:

```
1/3*x^3
```

but I want 1/3

Looks like mathematica_free only calculates indefinite integrals. http://integrals.wolfram.com ... so Sage would need to apply the limits after receiving the indefinite result. As a work-around you could define a function that passes the integrand to mathematica_free and then performs the difference after applying the variable limits.

If Sage wanted to calculate the definite integral as described in my previous comment,a simple change to sage/symbolic/integration/external.py could accomplish this. One wonders what would happen with wacky input/output though.

Thanks for comments!
