Interesting integral

  1. Jan 25, 2015 #1
    Is there any way of evaluating the following integral:

    [tex]\int sin{(\frac{2x+3}{x^2+3x-2})} dx[/tex]

    I have thought hard but cannot find an answer.

    Obviously, the denominator is the differential of the numerator. But a function is being taken of this fraction...

    I doubt it.
    No, the numerator (top) is the differential of the denominator (bottom).
