    [Solved] Integral Error

    The integral <cos(mx),cos(mx)> is supposed to equal 1 but I am not obtaining the result.

    Can someone see what is going wrong?

    It is the 2nd integral in the pdf.

    The problem is solved. In case you want to know, m and n have to be assumed to be integers; thus, making sin 0.
