What am I doing wrong here?
i just googled "ln derivative" and went to the first few hits
wathworld is legit, lots of good stuff there, mathtopia sp? was good i think
i havent done anything with math for a few years now so im a bit out of the loop
i used to try to use university web pages alot though, classes with notes online are super useful, and questions are pretty universal if you know what i mean :rick:

You just didn't use the chain rule right, see above post
edit: verified with my calculator (sort of). My calc minimized it a lil bit but it looks to be similar.
y=ln(x^4 + 5x^2)^(3/2)
use ln manip. to get
y=(3/2)(ln(x^4 + 5x^2)
then use the def of deriv of ln to get
y'=(3/2) [(1/(x^4 + 5x^2))(4x^3 + 10x)]
simplify
y'=(12x^3 + 30x)/(2x^4 + 10x^2)
basically y=ln(x)
y'=(dx/x)
but only for lower level stuff, dont do this in 253 or above
