Roberto wants to make $2.00 using dollars, half-dollars and quarters. how many different ways can he make $2.00?

(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.

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)
