Question

find d^2y/dx^2 if xlnx-y=0

Answer 1

y=xln x
use product rule to first find dy/dx
know the product rule ?

Answer 2

yes i know the product rule, but i though that because the equation was equal 0 i should use implicit differentiation

Answer 3

you can use implicit differentiation, in x ln x-y=0
you'll get the same thing.

Answer 4

(.....) -dy/dx = 0
(.....)=dy/dx<----implicit

xln x =y
(....) =dy/dx
