I intuitively would say: A generalized symbolic answer should contain {A, B, w1, w2, and theta}.

Some restrictions can be such as: {A, B. w1, w2, and theta}>0.

A generalized solution would not be affected by the relative relations between w1 and w2. Unless, solutions exist for special cases only.

Thanks Markiyan for your answer.

In fact I'm more intereseted in a generalized symbolic answer. is that posspile with Maple?

Also, you said that it's max(abs(A+B), abs(A-B)) in case w1 and w2 are multiples.

1- Do you have a more precise reference for that answer?

2- What if w1 and w2 are not multiples.
