Find the exact solution of the given initial value problem. Then apply Euler's method twice to approximate (to four decimal places) this solution on the given interval, first with step size h=0.01, then with step size h=0.005. Make a table showing the approximate values and the actual value, together with the percentage error in the more accurate approximation, for x an integral multiple of 0.2 xy=16x3y,y(3)=13,3x4 (Do not round until the final answer. Then round to four decimal places as needed.) Find the exact solution of the given initial value problem.
