Find the General Solution of the equations.

(a) r = a2t (b) r - 3as + 2a2t = 0 where r = ∂2z/∂x2 , s = ∂2z/∂x∂y, t = ∂2z/∂y2

(c) (2D2 + 5DD′ + 2D′2)z = 0 (d) ∂3z/∂x3 - 3∂3z/∂x2∂y + 2∂3z/∂x∂y2 = 0

Solution :- (a) r = a2t => D2z = a2D′z => ( D2 - a2 D′2 )z =0 -------------------(1)

where D ≡ ∂/∂x , D′ ≡ ...
