(Bonus - 6 points) Some practice with trigonometric functions - I have three equations describing three waves: y₁(x, t) = G cos(Ax + Bt), Y2(x, t) = G cos(Ax – Bt), P sin (Ux) sin(Mt). Y3 (x, t) = Here, all capital letters (G,A,B,etc.) are positive con- stants (scalars). (a) Classify y1,2,3 as a wave traveling to the right, a wave traveling to the left, or a standing wave. (b) What kind of wave is y₁ + y2? (c) If y3 = y₁ + y2, find P, U, M in terms of G, A, B.
