Find y' For Given Function
For this question, I decided to first distribute the (1/2). However, I got stuck as the picture will show.

Re: Find y' For Given Function
You will find this problem MUCH easier if you simplify the logarithm first: \displaystyle \begin{align*} \ln{ \left( \frac{x + 1}{x - 1} \right) } = \ln{ \left( x + 1 \right) } - \ln{ \left( x - 1 \right) } \end{align*}.

Re: Find y' For Given Function
Thanks. I thought about using the quotient rule for logs but it was just a thought. I will tackle this question again today.
