1.6. The sine function is given by the infinite series sin(x) = x-33 + x5 (a) What are the forward and backward errors if we approximate the sine function by using only the first term in the series, ie., sin(x) x, for r 0.1, 0.5, and 1.0? (b) What are the forward and backward errors if we approximate the sine function by using the first two terms in the series, i.e., sin(x)x - 3/6, for r 0.1, 0.5, and 1.0
