Hello everyone!
1. The problem statement, all variables and given/known data
Solving a relatively general equation representing a constant combination of 2 trigonometric functions.

2. Relevant equations
$$a\cos{(vx+p)}+b\cos{(ux+q)}=c$$

3. The attempt at a solution
I really don't have any idea for a general solution to this equation..

Best Regards

Not aware of any general analytic solution. Do you have a reason for believing such exists?
