Find dy/dx: y= xtan(u^2)/ln(x) This is just some Diff eqn review for my fluid mechanic class, and Im a bit rusty any help would be appreciated! I tried integrating both sides but I got lost when I tried to integrate for x...

You don't integrate to find a derivative... Also, what is ? Is it a function of or a constant?
u = 1+ x^3
Why didn't I know that? My psychic powers are a little off this morning... Anyway . You need to use the Quotient Rule, then the Product Rule, then the Chain Rule... See how you go.
y = tan(1+x^3)^2 (ln(x))*tan(1+x^3)^2 + 6x^3 sec^2 (x^3+1)tan(x^3+1) / ln(x)^2 I think thats about right just wasn't expecting that for a damn fluids class lol Thanks.
