Chapter 10.2, Problem 40E

(10k - 12)- (7 – 4n) x > (-6m) 22.Evaluate the given series k=3 n=2 m=1 O A. -108 O B. -52 O C. 3574 O D. -3482

(a) State the Maclaurin series for sin(r) and cos(r). You do not have to derive these. (b) Using series multiplication [as in example 13, 11.10] find the power series representation of the product, sin(r) cos(r) (c) Note that sin(2x) = sin(r) cos(r). Find the Maclaurin series for sin(2r) by modifying the known series for sin(x) that you stated in part (a). Does your answer match that of part (b)? (d) Use division of power series to find the Maclaurin series for tan(r).
