please let me know using matlab

1.6. The sine function is given by the infinite series sin(x) = 1 - + 3! 5! 7! (a) What are the forward and backward errors if we approximate the sine function by using only the first term in the series, i.e., sin(x) I, for I = 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)
