Define r and s as scalars r = 1.6 x 103 and s = 14.2, and, t, x, and y as vectors t = [1, 2, 3, 4, 5], x = [0, 2, 4, 6, 8], and y = [3, 6, 9, 12, 15]. Then use these variables to calculate the following expressions using element-by-element calculations for the vectors.
(a) G = xt + r/s2 (y2 -x)t
(b) R = r(-xt + yt2)/15 -s2(y - 0.5x2)t
