Can someone please go over what they'd do for this answer, possibly even the full answer so I can go through it, learn how it's to be done then move on with the next 5 questions I have!
Thanks in advance
This is the most recent problem I can't do!
State the contrapositive and give a proof of the contropositive:
If 1/2(a^2 + b^2) >ab then a/=/b (a not equal to b)
I guess the contrapositve is If Not a/=/b then Not 1/2(a^2 + b^2) > ab
But now what?!
