Homework Statement
3 waves are represented by these 3 waves inteferring:
cos(Θ-π), cos(Θ+π), 3cos(Θ)?
cos([tex]\theta[/tex]-[tex]\pi[/tex]), cos([tex]\theta[/tex]+[tex]\pi[/tex]), 3cos([tex]\theta[/tex]).
If I want to diagram these, does the cos([tex]\theta[/tex]-[tex]\pi[/tex]) and cos([tex]\theta[/tex]+[tex]\pi[/tex]), cancel each other out?
Do I need to convert them to sine functions or can I leave them cosine functions?
