What is the domain of the function on the graph?

all real numbers
all real numbers greater than or equal to 0
all real numbers greater than or equal to –2
all real numbers greater than or equal to –3

(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.

If value of cos330° is √3/2 then find tan165°.
