I am not asking for the formulas. I already know those! What am I asking is if this is an appropriate application of the Harmonic Addition Theorem. Is it?

I have a mathematical model which, in part, does a calculation based on the location of certain points on a unit circle. I am just working in 2d so for some arbitrary values of a,b,c,d,e,f In the case of the unit circle equally divided so that I have three points on the unit circle (120°...

its just Hooke's law, basically, F=-kx. We have multiple springs so we have a sum of the forces. The position x is given with the trig functions because the springs are arranged in a co-circular way.

Oh, I assumed people in this forum were familiar with basic analytic geometry. Let me explain. You see, in general, an ellipse has parametric form x=a cos \Theta y=b sin \Theta In my example problem we see that with some simplification we have a similar expression. In my software experiments I...

This problem is actually a simplification of something seen in a data visualization tool. I think it is interesting in that it can be "translated" to a Hooke's Law problem. Unfortunately, I am not sure how to proceed... Suppose I have a point mass tethered to several springs. The springs are...
