Question

Verify that the equations

i)   z =\sqrt{2x+a}+ \sqrt{2y+b} and

ii)   z^{2}+\mu = 2 ( 1 + \lambda ^{-1}) (x+\lambda y )

  are both complete integrals of the PDE z =\frac{1}{p} + \frac{1}{q} Also show that the complete integral (ii) is the envelope of the one parameter sub-system obtained by taking b=\frac{a}{\lambda } + \frac{\mu }{1+\lambda } in the solution i).

To solve this problem numerically and verify the given equations, let's break it down step-by-step: ### Step 1: Given Equations We have two equations: 1. \( z = \sqrt{2x + a} + \sqrt{2y + b} \) 2. \( z^2 + \mu = 2 \left( 1 + \lambda^{-1} \right) (x + \lambda y) \) We are also provided with the partial differential equation: \[ z = \frac{1}{p} + \frac{1}{q} \] where \( p \) and \( q \) represent the partial derivatives of \( z \) with respect to \( x \) and \( y \), respectively. ### Step 2: Taking Partial Derivatives For the first equation, we take the partial derivatives with respect to \( x \) and \( y \). #### ________ ___ ______ ____ ___.
