8.What is an equivalent expression to -2x + 7

(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.

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

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
