1. Given Y = ln [ (x+1)^3/((x^2)-1)^(1/2), find y' 2. I came out with the following answer to this question: (3x-4)/((x^2)-1) How ever, I typed the question into an online derivative calculator (to hopefully check my asnwer as I have no answer key, and want to make sure I'm on the right path), but it came up with a completely different answer: (2x-3)/((x^2)-1) Could anyone point me in the right direction...my answer worked out nicely: factored, cancelled etc. but I'm worried its not correct. Thanks for the check!
