3. Tara and Joyce each put the same amount of money in a new bank account. Tara's account earns 2.25% simple interest and she earned $1.35
in interest after 1 year. Joyce's account earns 4% simple interest. How
much interest did Joyce earn in her account after 1 year?
a) $2.40
b) $2.60
c) $1.80
d) $2.10

(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.
