hello, i am supposed to use the two variable chain rule to confirm that changing variables from (x,y) to (v,w) with v=x and w=y/x leads to:(adsbygoogle = window.adsbygoogle || []).push({});

\partial{v}=\partial{x} + w\partial{y}

and \partial{w}=x\partial{y}

it seems to me that the first line should read \partial{v}=\partial{x} = w\partial{y}

is this true? i am a bit rusty on multivariable calculus
