What is the awnser to (x+2)2

Is a currency whose value is tied to another currency, meaning that the exchange is fixed

What are correct trigonometric ratios that could be used to determine the length of ln

(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.
