Can some one help me plsss

(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.

Write the following as a base and exponent

Table which ratio is equivalent to 3: 7? 6: 7 3: 21 24: 56 15: 30
