Chapter 8.2, Problem 7P

In each of Problem 7 through 12, find approximate values of the solution of the given initial value problem at $t=0.5,1.0,1.5,\text{and2}\text{.0}$.

a) Use the Euler method with $h=0.025$.

b) Use the Euler method with $h=0.0125$.

$\begin{array}{cc}y\text{'}=0.5-t+2y,& y(0)=1\end{array}$
