Let A be the augmented matrix of a linear system. Find the solution for this
linear system.

(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 sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

State if the two triangles are congruent. if they are, state how you know?
