Consider the waves represented by the following functions. (a) y = 4 sin (3x − 15t) (b) y = 6 cos (3x + 15t − 2) (c) y = 8 sin (2x + 15t) (d) y = 8 cos (4x + 20t) (e) y = 7 sin (6x − 24t) rank the waves represented by the above functions from the largest to the smallest according to the following conditions. (use only "> " or "=" symbols. do not include any spaces or parenthesis around the letters or symbols.) (i) their amplitudes (ii) their wavelengths (iii) their frequencies (iv) their periods (v) their speeds
