Calculate 5+i2/1+i, 5+i3/1-i

(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.

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41
