Question

wolfram alpha error!?
Is it just me or Wolfram Alpha chokes on deriving ln(x^2+y^2)

Answer 1

might be how you input the question

Answer 2

try it yourself, it doesn't seem to work

Answer 3

I tried it and it worked fine. If you want I can just show you how to do it.

Answer 4

derivative of ln(x^2+y^2) is supposed to give y'=2x/(x^2+y^2-2y)

Answer 5

I would too

Answer 6

The derivative of that function doesn't equal y'=2x/(x^2+y^2-2y). It's supposed to be y'=2x/(x^2+y^2)
