The figure shows two semicircles centered at g and h. point b is on both semicircles. line df touches each circle at one point only, points f and e. if de = 4 and ef = 8, what is the scale factor applied when triangle deh is dilated to make triangle dfg?

(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.
