## Homework Statement

sin

^{-1}3x+ln sqrt(x) sqrt(sec x)

## Homework Equations

## The Attempt at a Solution

I have a very long solution, which is hard to type in. My final answer is:

-3cos3x/sin

^{2}3x + (1+xtanx)/2x

I don't check it with a derivative calculator because usually it makes mistakes. I ask someone to solve the problem and see if this is the right answer.

Thank you!
