not calculate. Prove it.?
du should be -2
umm idk
2x^2 + 2y^2 = 4xy
2x^2 +2y^2 - 4xy = 0
2x^2 + 2y(y-2x) = 0
U = y-2x
dU = -2
nope im wrong I can tell.
I needed to sub a value for all of y not just part
x^2+y^2=2xy -------- x=? and y=?
0
you completely miss the point.
you're not to calculate shit. Prove that this is valid for constant y
shit is too simple. For every a of the real numbers is a^2 >= 0
substitute a by (x-y)
so (y-x)^2 > 0
multiply by 2 : 2(x-y)^2 >= 2*0 = 0
Break the brackets: 2*(x^2-2*xy+y^2) >= 0
multiply: 2x^2 -4xy + 2y^2 >= 0
and who doesnt see it now should quit math forever.

well that was a rude way to put that, you should have said it was a proof at the start and not 2 comments later
whatever you got it done so thats all that counts

I've been doing my homework since 10 am. in the end for 7 hours through.
2 of them trying to debug a Check-mechanism which was screwed up in a way you'd allways get a Fail Message.
the only break I took was after 7 hrs to pay my rent and ride my bike 30 minutes through the rain. only to continue homework for 2 more hours after which I finally got to eat my first meal of the day.
ofc I'm a little on edge now.

ahh,I see~^^ It's good then~
for me,maybe I cannot call it as fetish,but I do like some kind of costumes~ like summer dress,halloween costumes,and some others~
tho I enjoyed an art as a whole~
