True or false? a triangle can be circumscribed about a given circle

(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.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
