(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 1 is divided by the sum of y& 4. the result is equal to 3 divided by 4 .find the value of m?

The parabola opens: y=√x-4 (principal square root) up down right left
