Math 104A Final Exam Winter 2009 1. (10 points) An amount ofP1dollars is put into an account at the beginning of years 1,2, . . . , N1.It is compounded annually at a rate orr(e.g.,r= 0.05 means a 5 percent rate of interest).At the beginning of yearsN1+ 1, . . . , N1+N2, a payment ofP2dollars is removed from theaccount. After the last payment, the account is exactly zero. The relationship of the variablesisP1(1 +r)N1-1=P21-(1 +r)-N2.IfN1= 30,N2= 20,P1= 2000, andP2= 8000, then what isr?2. (10 points) Consider the following iterative method to solvef(x) = 0:xn+1=g(xn),whereg(x) =x-f(x)f0(x)-12f00(x)f0(x)f(x)f0(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 toe-x= sin(x)located in the interval [0,1].3. (10 points) Find the coefficientsa0,a1
