What is the pattern of 110 150 what is the answer

If x = 12 and y = 3, what is the value of x - y 2? 81 6 3 18

(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.

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²
