1. The problem statement, all variables and given/known data
3 waves are represented by these 3 waves inteferring:
cos(Θ-π), cos(Θ+π), 3cos(Θ)?
cos(\theta-\pi), cos(\theta+\pi), 3cos(\theta).
If I want to diagram these, does the cos(\theta-\pi) and cos(\theta+\pi), cancel each other out?
Do I need to convert them to sine functions or can I leave them cosine functions?
2. Relevant equations
cos(Θ-π), cos(Θ+π), 3cos(Θ).
cos(\theta-\pi), cos(\theta+\pi), 3cos(\theta).
3. The attempt at a solution
