A harmonic function is analytic if it satisfies the Laplace equation. If $u(x,y)=2x^2-2y^2+4xy$ is a harmonic function, then its conjugate harmonic function $v(x,y)$ is $4xy-2x^2+2y^2+ \text{constant}$ $4y^2-4xy + \text{constant}$ $2x^2-2y^2+ xy + \text{constant}$ $-4xy+2y^2-2x^2+ \text{constant}$

GATE Mechanical 2014 Set 2 | Question: 27
The general solution of the differential equation $\dfrac{dy}{dx}=\cos(x+y)$, with $c$ as a constant, is $y+\sin \left (x+y \right )=x+c \\$ $\tan \left (\dfrac{x+y}{2} \right)=y+c \\$ $\cos \left (\dfrac{x+y}{2} \right )=x+c \\$ $\tan \left (\dfrac{x+y}{2} \right )=x+c$
