ln(y)

hi /sci/,

even with my notes for basic integration in front of me, I can't figure out the derivative of:

(x^2) - 3lny + (y^2) = 10

I'm sure it's something basic, but I can't figure out how to get around the derivative of ln(y) putting a y in the denominator.

d/dx(ln y = y'/y

if you want to integrate ln(y), you must use IBP / integration by parts.

but, to be honest, i don't even understand the question here ...

is this multivariable calculus, in which you're doing partial derivatives?  is this a double-integration problem?  differential equations?
