i can't grasp these concepts, 1-to-1 and onto have always annoyed me.
here's 1 question, (i don't know how to post symbols so Beta ..)
(C is Complex numbers)
Let Beta:<C,+> -> <C,+> by Beta(a+bi)=a-bi (that is, the image is a +(-b)i).
Prove Beta is an isomorphism of groups.
i have a lot of these problems but maybe a one may help me understand the rest
