find the derivative of this question:
\n" ); document.write( "======================\r
\n" ); document.write( "\n" ); document.write( "f'(x) = \"atan%28x%29+%2B+x%2F%281%2Bx%5E2%29+-+%281%2F2%29%2A%28x%5E2%2B1%29%5E%28-1%29%2A2x\"
\n" ); document.write( "f'(x) = \"atan%28x%29+%2B+x%2F%281%2Bx%5E2%29+%2B+1%2F%28x%5E2%2B1%29\"
\n" ); document.write( "f'(x) = \"atan%28x%29+%2B+%28x%2B1%29%2F%281%2Bx%5E2%29\"
