I am attempting to compute an approximation of the solution with the forward Euler method in [0,1] with step lengths h_1=0.2, h_2=0.1 given the initial value problem below dy/dz=1/(1+z)−y(z) y(0)=1 I am not sure what to do when I am given two step sizes instead of one. I know how to compute it if it was given with a step size. Am I supposed to find out the approximation for two different step sizes? Or is there anything I am missing?
