Christina is playing a board game. Her score was −275 at the start of her turn, and at the end of her turn her score was −640. What was the change in Christina score from the start of her turn to the end of her turn?

(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.
