I have tried using this method https://www.youtube.com/watch?v=V-LJWfuoCDs. But I am getting zero on one side thus cancelling $e^x$, which means that the the answer I get will not be in form of ln. Is this correct? Kindly help me solve it
What I did is I let $y$ be $(e^x – je^x)/(e^x+e^x)$. Then I said $y (2e^x) = e^j - je^x$. Solving further leads to cancellation of $e^x$. :( :(. i am supposed to teach this to students tomorrow. I don't really know what goes on. I think $J$ is a letter (constant) in this case
