Question

What is the first step in adding the wave functions y1 = Asin(kx - ωt) and y2 = Bcos(kx - ωt)?

Accepted Answer

Determine the resultant amplitude using vector addition.

Answer

Directly add the amplitudes.

Answer

Ignore the cosine function.

Answer

Subtract the smaller amplitude from the larger one.
