Lagrange’s method is used primarily for which type of PDEs?
Recall the section where we discussed Lagrange's method.
Given the PDE pz + q sin(y) = cos(x), apply Lagrange's method to find the general solution.
Focus on those auxiliary equations to find independent solutions.
For the PDE p^2 + qz = 2x apply Charpit's method and derive the complete solution in terms of x, y, and z.
Remember to utilize the nonlinear structure to set your ratios.
