Question

use implicit differentiation to find dy/dx x^2+2xy-y^2=2

Answer 1

if you are really intent on learning how to use implicit differentation; it would help if you did not just post all of your problems at once. Simply stay on a problem and work thru it with those who are wanting to help you.

otherwise it comes across as you simply wanting to get answers to your homework/test/whatever at our expense.

Answer 2

ok, let's start... what's dy/dx of the right side? hello? jmid?

Answer 3

x^2+2xy-y^2+x=2 this is a review though not homework, or test
