Question

find dy/dx where ln(xy) = e

where do i even start?!

Answer 1

convert ln(xy) = e to xy=e^e or
y = e^e/x = e^e*x^-1
now, find its derivative,
does this help ?

Answer 2

Hmm... not really :(

Answer 3

I have never seen that before. I can't find that in my textbook. do you know of ay other good tutorial sites?

Answer 4

which part that not really ?
