Why do we need complex numbers and what are conjugates and why do we need

(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 the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. t
