a) x^3 + x^2 - 4x + 30
b) x^3 - 5x^2 + 10x + 30
c) x^3 - 7x^2 + 16x + 30
d) x^3 - 7x^2 + 4x + 30

What aspects of lines have to be diffrent

Aphoto of a painting measured 13 x 17 inches the scale of the photo to the original painting is 1 inch to 3 inches. what is the size of this painting

(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.
