Correction.
To understand the recall some theory.
Equation of the form f(p,q)=0 i.e. the equation contains p and q only.
Suppose that z(x,y)=ax+by+c is solution of equation, then
p=∂x∂z=aandq=∂y∂z=b
substitute the above in equation f(p,q)=0 , we get f(a,b)=0 on solving this we can get b=ϕ(a) , where ϕ is known function. Using b=ϕ(a) , the complete solution of the given partial equation is
