Having a little trouble with this problem, i know im doing something wrong

Problem: f(x) = sin(6ln(x))

(my) Answer: Cos (ln(x))/x

If you need me to show my work i will, trying to get some other problem done. Homework is due at 11:55 tonight :(

Problem: f(x) = sin(6ln(x)) <<< what happened to the 6

(my) Answer: Cos (ln(x))/x <<< Incorrect - per above

Re: Differentiate the function.

Hi, the correct answer should be this:

d/dx sin(6*ln(x))
cos(6*ln(x)) * d/dx 6*ln(x)
cos(6*ln(x)) * 6 * d/dx ln(x)
cos(6*ln(x)) * 6 * 1/x
cos(6*ln(x)) * 6/x

Hope this helped. :D
