Practicing on Khan Academy, and I'm not sure about this step on L'Hôpital's rule (see attached). Where did sin(sqrt(x-1)) go?

everything makes sense if there is no sin in the question

hartnn (hartnn):

the question itself is probably \(\Large \dfrac{1}{\ln x}-\dfrac{1}{\sqrt{x-1}}\)

OpenStudy (anonymous):

Agreed, so probably a glitch?

hartnn (hartnn):

yup...typing mistake

Duly submitted as a bug, thanks. :)
