3.2.1 Fixed rate mortgage Consider a mortgage for $750,000 with a constant interest rate of 5% (r = 0.05) and a nnonthly payment p = $4,000. on Mat lab I. Implement Euler's method for Eq. (2) with step size h = 0.01. Use a while loop to run the method until the mortgage is paid off (y = 0) and determine when it is paid off 2. Plot the numerical solution y(t) and the true solution to equation (2) with the parameters given here in the same graph and compare the two. 3. Repea t the previous item for a step size h = 0.5 and comment on the difference. 3.2.1 Fixed rate mortgage Consider a mortgage for $750,000 with a constant interest rate of 5% (r = 0.05) and a nnonthly payment p = $4,000. on Mat lab I.
