This is a problem where we are supposed to design a cam..

GIVEN

For the same harmonic motion describe above, show that for a fiven value of C and L, the cam angle must be limited by the relationship..

in order to avoid pointing or cusp of the cam surface.

I know a cusp or point occurs on the cam surface when both and

I also know that

so...

So plugging in

I just need help simplifying so i can get the relation above
