Consider the differential equation $y^{\prime}=y-2$ with initial condition $y\left(0\right)=1$.

a) Use Euler's method with 4 steps of size 0.2 to estimate $y\left(0.8\right)$

I know how to do this by hand; however, I have maple 12 installed and was trying to figure out how to do this with Maple, and then make a graph showing each step of the function. Any suggestions. I have tried looking on mapleprimes, but it keeps pointing me to functions for newer versions of maplesoft, which I don't have....
