Question

Zpq=p+q solve by using charpits method?

Answer 1

both are equal

Step-by-step explanation:

both are equal if you can solve the both of these then you can get equal answers you can put value and then try to solve it

Answer 2

Step-by-step explanation:

given pde is zpq=p+q

let the solution be z=f(u) , where u= x+ay

p=dz/du q=adz/du

now sub p and q in pde ,then

z(dz/du)a(dz/du)=dz/du+adx/du

az(dz/du)^2=dz/du(1+a)

zdz=(1+a)/adu

I.O.B.S

then z^2/2=((1+a)/a)u+c

which is required soln
