Q1: Solve the following initial value problem over the interval from t=0 to 2 where y(0)=1 with h=0.25 using Euler's Method and Heun's method without iteration. Knowing that the analytical solution for this ODE is given below as well, calculate the relative true error in percentage for your solutions. dy = yt³ — 1.5y dt y = (-1.5t)
