i'm trying to read and understand from my textbook how to do this method and i am lost. can anyone explain it to me?

my problem is...

dy/dx= x-y^2

y(0)=1

x is less than or equal to 2 and greater than or equal to 0

change in x= .25

use eulers method to approximate the solution of the initial-value problems over the stated interval. present the answer as a table and a graph.

thank you so much i appreciate it
