It looks pretty much like a sinewave, but still has all the harmonics and <br>
the timbre of a triangle. That's pretty cool. Another example of <br>
substantially different looking waveforms with the same sound. Also goes to <br>
show that what initially *looks* like a decent sinewave can actually have <br>

We use to call this waveshape "designers sinewave", since it's so often seen in illustrations of sinewaves, but totally wrong and in best case a misunderstanding of how sinewaves relate to circles. :-D</div><div><br></div><div><a href="https://www.desmos.com/calculator/vtai9amxtl">https://www.desmos.com/calculator/vtai9amxtl</a></div><div><br></div><div>What's interesting (and a bit annoying) is how it's not a perfect semi-circle but very very close... why would math bother with getting so close to a shape but not really mean it?</div><div><br></div><div>/mr</div><div><br></div></div></div>
