<p>Hey Folks,</p>
<p>I've got a pretty simple question here. I use maple to check my work and I'm wondering how  to get a numerical approximate of a Riemann sum containing a trig function. I don't want sin in the answer. For example:</p>
<p><maple>(1/40)*Pi*(Sum((1/40)*sin*i*Pi, i = 1 .. 10))</maple></p>
<p>A<maple>pproximates to 0.33928 sin.</maple></p>
