If $u(x,y)$=$2xy$ , then $v(x,y)$ may be expressed as $-x^2 + y^2 + $ constant $x^2 – y^2 +$ constant $x^2 + y^2 +$ constant $-(x^2 + y^2) +$ constant Calculus gateme-2016-set1 calculus complex-variables + – Arjun asked Feb 24, 2017 • recategorized Mar 5, 2021 by Lakshman Bhaiya ♦Arjun 28.5k points answer See all 0 reply
