We are given 2 wave equations as follows:

y1 = 25 sin(wt - pi/4)
y2 = 15 sin(wt - pi/6)

wt=omega * time

Find the resultant amplitude, phase, and equation for the wave based on the superposition principle. The 2 equations above have the same frequency. Any help would be great. Thanks

Somebody answer this question cause I need to know this as well!! :D

This link might help.
