Simplify the expression 5a – 2b – 3 + 2b – 6a
A. –4
B. 2a – 4b
C. –a – 3
D. a – 3

(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.
