Show that yı(x) = x sin x and y2(x) = x cos x are solutions of the associated homogeneous equation. %3D 3. Use the Wronskian test to determine if y1 and y2 are linearly independent for ar > 0. 4. Write down the solution Yn(x) of the associated homogeneous equation. 5. Use the formulas in the course notes for the method of variation of parameters to find a particular solution yp(x) of equation (1). Hint: you will need to re-write the ODE in standard form in order to identify the non-homogeneous term in the formulas. 6. Write down the general solution to equation (1). 7. Find the solution to equation (1) that satisfies the initial conditions 37 y(T/2) and y(T/2) = 0. 2 8. Use Matlab to plot the solution to the IVP in 7 for 0 < x < 30. Attach the plot to your assignment and describe the solution behaviour as x → 0.
