<p>
        The first problem with this function, is that the singularity is at &#960;/2, so
        if we're integrating over (0, &#960;/2) then we can never approach closer to the
        singularity than &#949;, and for p less than but close to 1, we need to get <span class="emphasis"><em>very</em></span>
        close to the singularity to find all the area under the function. If we recall
        the identity <code class="literal">tan(&#960;/2 - x) == 1/
