Analytical integral

  1. Dec 1, 2014 #1
    can someone suggest a method to solve an integral of the form analytically?
    ##\int \left[\frac{1}{(1+x^{2})}\right]^{-n}e^{-x^{2}}dx##

    Is the bracket a floor function? Otherwise you can use the reciprocal to get (1+x2)n. In that case the infinite integral can be done, but the indefinite integral can be expressed only in terms of the erf.
