What missing piece of information is needed to prove the triangles congruent using SAS?

If f(x) = 2x + 2 and g(x) = x? , what is (gºf)(2)?

(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.
