Title: Partial Derivatives
Post by: SGVaibhav on April 02, 2010, 07:19:15 pm: Hi,
i cannot find the partial derivative for this thing...
this time,i tried lots, searched over the net, and after 0% sucess, im asking it now

$\[ \frac{\partial }{\partial x}[ \arctan([1/(x y^2 z^3))$

the main part which i dont get is differentiating the first part of (arctan x).I can later derive $1 / xy^2z^3$ easily.
but the main thing which is how to derive the arctan of $1/xy^2z^3$
