mathslover, i have that textbook with me :P..

i ll go through all the sites.. thanks guys

i just want to be able to explain to them why we consider the domain, the range, the co - domain, what is the root meaning of that,
I am actually a physics teacher, and i always introduce a concept in such a way that, they understand why it had to be introduced, and how those concepts make things simpler... so i wanted the same for this chapter.. i ll use all the links you guys posted

thanks again :)
