Find the area of the shaded part . figure one and two .

Given the following similar triangles what is the area of triangle b ? a) 1 b)1.8 c)3.2 d)5

(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.

Me because some of question i don’t understand
