Porter is buying t ride tickets at the county fair. He receives 3 tickets for every dollar, d, that he spends. Which is the independent variable and which is the dependent variable?

(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.

Find the roots of the equation below. x^2 - 6 + 9 = 0
