1) Derivative of f(x)=sin(ln(x))

I obviously don't know what to do...I Googled and found out that the derivative of ln x=1/x, so I tried doing the derivative of sin(1/x), but that didn't work, and I wasn't really sure how to do it.

2) Derivative of (4 - ln(x)) / (2 + ln(x))

Again, no clue how to do this, so any help is appreciated.

Thanks in advance!
