Question

Find dy/Dx by logarithmic differatiation of the integral of dx/e^x

Answer 1

?? What does that even mean? How does y relate to x? Did you write "Dx" on purpose or should it be "dx"?

Answer 2

No need to be rude, it was a typo yes it should be dx

Answer 3

Not being rude at all. The question simply makes no sense. Can you type in the whole, complete, exact problem?

Answer 4

That is the problem, word for word, I can't input symbols like the integral though

Answer 5

We are to evaluate \(\dfrac{dy}{dx}\int\dfrac{dx}{e^{x}}\)? Really?

Answer 6

You're are finding dy/dx by using logarithmic differentiatio, so yes

Answer 7

Very odd.

1) There is no need for logarithmic differentiation, so I have to wonder if we have the right problem. Maybe it's printed incorrectly?

2) It just isn't clear if y IS the integral or somehow, part of it, or some odd chunk of the derivative notation.

3) \(\dfrac{d}{dx}\int \dfrac{dx}{e^{x}} = e^{-x}\)

Are there surrounding problems that might give a clue to what it wants?
