9. Sally and Peter are saving to buy a car. They deposit $10,000 into a savings account that
pays simple interest at a rate of 15% per year.
If a car costs $17,500, in how many years will
they have enough money to buy the car?

(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 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
