Calculus 1: Ch 5.1 Derivative of e^x and lnx (14 of 24) More Natural Log Examples 1

In this video I will solve, dy/dx=?, some more common natural log examples 1: y=ln[s/(1+x^2)].

Next video in this series can be seen at:

I tried using it with the quotient rule and it was so darn difficult. The damn (1+x^2)^2 just ruined all my efforts. Is it even possible to do it that way even if it is harder.
THis is what I got (1+x^2)^2 - 2x / x(1+x^2)^2, basically it is the same as the answer exceot for the power of two and I had no clue how to simplify it after that.'
But thank you so much for your videos. Learning everyday.
