Which fraction is equivalent to 1 /4 ? a. 1 /8 b. 2/5 c. 2/6 d. 2/8

(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.

Is the figure congruent? yes or no?

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
