Write an expression that can be used to check the quotient of 646 divided 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.

What is the y intercept of f(x)=(1/2)^x?

Write an equation for the function that includes the points (1,4/5) and (2,2/3)
