Trigonometry hellllllpppppppp asap

(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.

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
