A man walks around a field once.
a runner runs around the field 6 times in the same time
the walker walks at 3m/s
calculate the speed of the runner.

(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.

How do you use the elimination method for this question? explain, because i really want to understand!
