Using the Logarithmic Differentiation find the derivative of $y=\sqrt{x(x-1)/(x-2)}$...so I tried,but the result is not correct..can you show me a hint?
so $\ln y= 0.5\ln[x(x-1)/(x-2)]$
$\ln y=0.5[\ln x+\ln(x-1)-\ln(x-2)]$
$\ln y=0.5\ln x+0.5\ln(x-1)+0.5\ln(x-2)$
$y'=0.5\ln x+0.5\ln(x-1)-0.5\ln(x-2)[\sqrt{x(x-1)/(x-2)}]$
