Please don't copy past the answer thats completely wrong. Use Matlab to answer this question. Please help me out I really need help on it. Im not good at Matlab. If you doing copy and pasting answer don't answer my question. I need except good at Matlab now how to answer this question.

= = = = = e Using the RK4 method, give the numerical approximation for the IVP: y' ty; y(0) = e; with a step size of h 0.5 for the point at t 20. How does this compare to Euler's Method (e.g. simply using the k values to approximate this ODE)?. The exact solution to the IVP above is y(t) = t? /2+1. In a single figure, plot the results of RK4, Euler methods and the exact function (thus, your plot should contain 3 lines). To show the full Y-range, the Y-axis should be plotted using a log-scale, however the X-axis should remain linear. To do this, type set(gca, YScale,log) on the line below that used to create the plot. Make sure that your figure has a legend that describes what each line corresponds to
