    Looks fine, except the antiderivative of 1/(1+x^2) is inverse tangent, or arctan, sometimes written tan^(-1), but tan^(-2) doesn't make much sense.

    And whenever you find an antiderivative, it's a good idea to check your work. If you take the derivative of your answer, you should get the integrand.
