This is known as the boundary value problems of differential equations .This research studies the solution of the set of Partial Differential Equations of parabolic and hyperbolic-hyperbolic type with boundary conditions imposed in different regions of the plane x o y . This research has been proving the theorem of uniqueness and the existence of the solution. 2023 2023 08 16 10.54216/GJMSA.030201 https://www.americaspg.com/articleinfo/33/show/1552
