Brigitte simplified the expression (7.4×10 to the 6th power) ÷ (5×10 negative 2 power) as 1.48 × 10 to the 9th power do you agree with her answer ? explain your reasoning

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
