PLEASE HELP I NEED IT 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.

The vertices of a triangle are a(7,5), b(4,2), c(9,2). what is m

Is it true or false i’m trying to pass this test so i can leave school
