Dear All--


The following was originally posted by Mahir Abrahim under Equation driven curves: cool equation, in response to: Kevin De Smet on May 6, 2010.


Wave Spring with radius R, height A, and n waves

x: R*cos(2*pi*t)

y: R*sin(2*pi*t)

z: A*sin(n*2*pi*t)

t1: 0

t2: .999 (SW won't do a closed loop)


How did he arrive at this equation. Is it the way it is made. If so, where can I find references to the same, else what are those sources from which this can be derived.
