a) Solve the following 2nd order ordinary differential equation using ode45 to find y(t). Here L = 5. Use a time span ranging from 0 to 30 with plenty of time values in between. Once you have the solution, have your program plot it versus time (time in the x-axis). b) Solve the following integral using int and display the result on the command window.
