 Recognitions: Homework Help To get the answer you have listed your function must be $\ln \sqrt{1+x^2}$ and not $\sqrt{\ln(1+x^2)}$. You can write $\ln \sqrt{1+x^2}=\frac{1}{2}\ln (1+x^2)$, perhaps this form is less intimidating?

## differentiating

so the 1/2 just stays out the front without it being differentiate, i thought it dissapeared? thanks for the replys
