MATLAB help please!!!!! 1. Use the forward Euler method Vi+,-Vi + (ti+1-tinti , yi) for i=0.1, 2, , taking yo-y(to) to be the initial condition, to approximate the solution at 2 of the IVP y'=y-t2 + 1, 0 2, y(0) = 0.5. t Use N 2k, k2,...,20 equispaced timesteps so to 0 and t-1 2) Make a convergence plot computing the error by comparing with the exact solution, y: t (t+1)2 exp(t)/2, and plotting the error as a function of...
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...
Consider the ODE dy/dt = -y(1-(y/T))(1-(y/K)) where 0 < T < K. (a) Draw a phase line and determine the stability of each equilibrium point. (b) Draw a graph in the yt-plane showing several solutions and their long term behavior. (Remark: Solving this ODE isn’t necessary!)

Use Taylor's second order method to approximate the solution. y'=-5y+5t^(2)+2t, 0 ≤ t ≤ 1, y(0) = 1/3,with h = 0.1 Also, compare relative errors if the actual solution is: y=t^(2) + 1/3 * e^(-5t)

In the previous lecture this method was explained. Recall that an ODE of the type dy/dr+py be rewritten as may 讐-劘塭 dr with ydl/dx- Ipy from where /(x) can be derived The complete solution of this ODE then is a sum of two terms: a term y. which is a solution of the ODE rewritten as d(ly)/dx- lq and a term y2, which follows from solving the homogeneous equation (the ODE with q-0 Task Solve two differential equations and determine...
