Two sine waves have equal peak to peak amplitudes 81 but are out of phase by 90 degrees. What is the peak to peak amplitude of the resultant wave.


I have no idea how to start this question, could someone give me guidance?

Graph
[tex]40.5sin(\omega t-\frac{\pi}{2})[/tex] and [tex]40.5sin(\omega t)[/tex]
The points on the graph where these functions intersect are where the resultant will have its maximum (and minimum) amplitudes.
