1) Solve the problem below with (1) power series solution, (2) numerical solution with central difference for both first and second order derivative. Hint: You can find the value of y(0+At) by using the forward difference formula for the first derivative, and the initial values you are provided. Try At values of 1, 10, 100, and 1000 milliseconds. Show how the function changes between 0 and 5 seconds on a graph for each one, comparing the numerical solution to the power series solution. 4ty" 6ty' + 5y = 18t4 17t 7t 2t, y(0) = 0, y'(0) = -2, y(t) = ? - 2) After solving this problem, discuss what happens if I tell you that y'(0) = 2 and not -2. 3) Then, find the solution for y'(0)=2, if the coefficient for the RHS term with t is 2 and not -2 also
