What is the probability of 26/100 19/100 and 55/100

How many sides does a regular polygon have if each exterior angle measures 72a.3b.4c.5d.6

(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.

Hello can you me find all the products
