Obtain the general solution of a non-homogeneous ODE y'''+2y''-5y'-6y=100e^3x + 18e^-x. Verify your solutions using MATLAB.
y=yh+yp = c1e^x + c2e^2x+c3e^3x + (7+10x)e^3x + (1/2 -3x)e^-x
y=yh+yp = c1e^-x + c2e^2x + c3e^-3x + (7+10x)e^3x + (1/2-3x)e^-x
y=yh+yp = c1e^-x + c2e^2x + c3e^-3x + (7+10x)e^3x + (1/2 - 3x)e^x
y=yh+yp = c1e^-x + c2e^2x + c3e^-3x + (10+7x)e^-3x + (1/2 +3x)e^-x
Keep trying to figure this and not coming up with the correct solution. Could someone work it out please?
