HELP PLEASE!! THIS IS A POP QUIZ AND I REALLY WANNA PASS D:

(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.

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7); m=-3/2

Me with this one question, and i'll upvote the brainliest answer
