. You are given the following info: The annual effective interest rate is 4%. A is the present value (i.e. value at time t = 0) of a four year continuous annuity where the payment rate is described by plt)=4t, where t is time in years. Find A. Give your answer as a decimal rounded to two places (i.e. X.XX). Note: You could probably do this one by hand (integration by parts...right?), but I would just use something like Mathematica or Wolfram Alpha. . You are given the following info: The annual effective interest rate is 4%. S is the future value (i.e. value at time t = 0) of a four year continuous annuity where the payment rate is described by plt) = 4t, where t is time in years. Find S. Give your answer as a decimal rounded to two places (i.e. X.XX). Note: If you got (9), then (10) shouldn't be too bad. . You are given the following info: The annual effective interest rate is 4%.
