ar angle &#945;, where <span class="emphasis"><em>m = sin<sup>2</sup>&#945;</em></span>.

<p>
          In our implementation, these functions all take the elliptic modulus <span class="emphasis"><em>k</em></span>
          as the parameter.
        </p>
<p>
          In addition the variable <span class="emphasis"><em>u</em></span> is sometimes expressed
          as an amplitude &#966;, in our implementation we always use <span class="emphasis"><em>u</em></span>.
