Differentiating both sides gives .
Why do you need to do this?
Could someone show me how to get the derivative of both sides of this equation? I can't quite seem to figure it out. I have an answer, but I'm not sure it is not correct. Thanks for looking.
Here is what I have so far:
y= ln x, so x= e^y
which gives 1= e^y dy/dx
then 1/e^y= dy/dx
which gives 1/e^lnx=dy/dx
and lastly dy/dx= 1/x
Good or not so good?
