Question

what is partial derrivative with respect to
x and y
1/ln(x^2+y^2)

Answer 1

partial derivatives treat the other spatial variables as constants

Answer 2

therefor the partial derivative with respect to x will treat y as if it were a constant

Answer 3

so when doing partial for x imagine y is 1:)

Answer 4

^took the words out of my.... fingers

Answer 5

:)

Answer 6

when derrivate the equation with respect to x we must take y as constant
