Problem 19.1. Find the amplitude, period, a
phase shift and the mean of the following si-
nusoidal functions.
(a) y = sin(2x - 7) + 1
(b) y = 6 sin(2x) - 1
(c) y = 3 sin(x + 2.7) + 5.2
(d) y = 5.6 (sin (x-7) – 12.1)
(e) y = 2.1 sin ( + 44.3) – 9.8
(1) y = 3.9 (sin(22.34(x + 18)) -- 11)
(g) y=11.2 sin ((x -9.2)) + 8.3
