Question

Implicit differentiation:
x^2+y^2=(2x^2+2y^2-x^2)
I got 0
that does not feel right

Answer 1

y^2 = 0

Answer 2

make sure you are doing the actual problem that was assigned...

Answer 3

do you know what i did wrong?

Answer 4

you misread the problem, I'm guessing... since the problem as it is written is utterly trivial

Answer 5

that is the problem

Answer 6

cool. so what's the derivative of the horizontal line y=0?

Answer 7

so it is 0 then?

Answer 8

yes

Answer 9

thanks
