Hi! looking for some help here on this page (all questions)

(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.

Find the value of x for which abcd must be a parallelogram -9-6x x-30

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol
