Math 104A Final Exam Winter 2009 1. (10 points) An amount of P 1 dollars is put into an account at the beginning of years 1 , 2 , . . . , N 1 . It is compounded annually at a rate or r (e.g., r = 0 . 05 means a 5 percent rate of interest). At the beginning of years N 1 + 1 , . . . , N 1 + N 2 , a payment of P 2 dollars is removed from the account. After the last payment, the account is exactly zero. The relationship of the variables is P 1 (1 + r ) N 1 - 1 = P 2 1 - (1 + r ) - N 2 . If N 1 = 30, N 2 = 20, P 1 = 2000, and P 2 = 8000, then what is r ? 2. (10 points) Consider the following iterative method to solve f ( x ) = 0: x n +1 = g ( x n ) , where g ( x ) = x - f ( x ) f 0 ( x ) - 1 2 f 00 ( x ) f 0 ( x ) f ( x ) f 0 ( x ) 2 . (a) (5 points) Does the method converge? What is the rate of convergence of the method? Justify your answer. (b) (5 points) Find, using this method, and to within 10 - 10 , the solution to e - x = sin( x ) located in the interval [0 , 1].

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
