i have the answer for second question i just need question 3 please

Solve the following problem with the Euler method: 2dx2d2y+3dxdy+3.125y=sinx where y(0)=5 and y(0)=3. Solve from x=0 to 5 with h=0.5. Find the error considering the exact solution is y(x)=e0.75x(5.292237cosx+6.859589sinx)0.292237cosx+0.109589sinx Display the analytical and numerical results on the same graph. Question 3: Develop a program in a language of your choice for the classical fourth-order Runge-Kutta method. Test this program by solving the question- 2
