(b) What additional information is needed to prove the triangles are congruent by the SAS Postulate? Explain.

(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.

Is the square root of 4 plus the square root of 16 rational?
