Homework Statement
The question asks us to find the superposition of 2 waves where y1=3cos(4x-1.6t) and y2= 4sin(5x-2t) and find the superposition of the waves y1 + Y2 at x=1 and t =0.5
Homework Equations
The Attempt at a Solution
Okay, what confuses me. is my teacher explained how to work with waves with the same amp, but not different and what do these equations give you. What does y1 mean? Is it the vertical distance?
The answer is not just plug in x and t, then add y1 + y2. I am so confused! please help! I know the waves are going the same way because of the sign but that is where my knowledge stops.
t is in s and x is in cm
And I got the answer from the back of the book.
