Please answer the question in the Pic thanks

Every rhombus is a square. true false

(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.

What is the difference between –12 and –5? what is the distance between –12 and –7 on a number line? units
