What is the surface area of the shaded front face of the composite solid?
18 square centimeters
26 square centimeters
32 square centimeters

Me find the measure to side a and the process to solve the problem you appreciate it : )

(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.

Ineed me i stuck and i don’t want to get it wrong
