Use MATLAB’s ode45 command to solve the following non linear 2nd order ODE: y'' = −y' + sin(ty) where the derivatives are with respect to time. The initial conditions are y(0) = 1 and y ' (0) = 0. Include your MATLAB code and correctly labelled plot (for 0 ≤ t ≤ 30). Describe the behaviour of the solution. Under certain conditions the following system of ODEs models fluid turbulence over time: dx / dt = σ(y − x) dy...

A.9. First-order linear non-homogeneous ODEs having one dependent variable are of the form dy + P(x)y = f(x). Beginning with yp = uyż, where yı = e-SP(x)dx and is thus a solution to Y + P(x)y = 0, and given that the general solution y = cyı + Yp, use variation of parameters to derive the formula for the general solution to first-order linear non-homogeneous ODES: dx y = e-SP(x)dx (S eS P(x)dx f(x)dx + c). You may use the...
