Ineed i don’t understand ratios and stuff like this.

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c?

(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.
