I'm working on the MSP tutorial 22, and I'm just not understanding the math in "constant distance xfade."

https://docs.cycling74.com/max5/tutorials/msp-tut/mspchapter22.html

Mostly it's the little things that are throwing me off. Why is 512 the divider for 0-64? How does a .75 make the cosine into a sine wave?
