Will give brainliest sum of arithmetic series (sigma notation) find the numerical answer to the summation given below. (image shown below)

(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.

Place the following steps in order to complete the square and solve the quadratic equation,
