I'm not too familiar with multi-variable calculus, but I'll try my best...\r

\n" ); document.write( "\n" ); document.write( " $\"du%2Fdx+=+%281%2F2%29%281%2Fsqrt%28xy%29%29%28y%29\"$ , applying the chain rule. Here, y is treated as a constant.\r

\n" ); document.write( "\n" ); document.write( " $\"du%2Fdy+=+%281%2F2%29%281%2Fsqrt%28xy%29%29%28x%29\"$ by the same logic. Therefore, $\"%28du%2Fdx%29%2F%28du%2Fdy%29+=+y%2Fx\"$ . \n" ); document.write( "
