Please help me find the value of x!!

(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.

What could explain what happened when the time was equal to 120 minutes

In the geometric progression –3, 12, −48… what term is 3,072?
