Find the complete integral of partial differential equation
z^2 = pqxy ?
I have solved this equation till auxiliary equation:
dp/(-pqy+2pz) = dq/(-pqx+2qz) = dz/(2pqxy) = dx/(qxy) = dy/(pxy)
But I have unable to find value of p and q.
p = ∂z/∂x q = ∂z/∂y r = ∂²z/∂x² = ∂p/∂x s = ∂²z/∂x∂y = ∂p/∂y or ∂q/∂x t = ∂²z/∂y² = ∂q/∂y
