Partical derivatives ` (delf)/(delz)` example

Postby admin » Thu 17 March, 2011 11:38

if x,y and z are independent variables and
`f(x,y,z)=xsin(y+3z)`, then
= `xcos(x+3z)del/(delz)(y+3z)`

How to:
to show `(delf)/(delz)` we use \`(delf)/(delz)\` but if we want `del/(delz)` then we don't need pranthesise around del and \`del/(delz)\` will work fine like this: `del/(delz)`
