(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.

If f(x)= 3x+6 which of the following is the inverse of f(x)

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
