Janet must paint her outdoor cicular tabletop

(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.

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.
