How do I take the derivative of
Welcome to PF!
Hi lreichardt! Welcome to PF!
Just use the chain rule: derivative of ln, times the derivative of x/(x-1).
so, (x/1)(quotient rule of x/(x-1)? =
ooh dear …
better go the easy way … simplify it first …
ln(x/(x-1)) = ln(x) - ln(x-1) … now differentiate!
Chain rule = The difference of the derivative of the "Outer" and derivative of the "Inner", put simply.
Thanks all, figured it out.
