Доброе время суток. У меня задача по дисциплине "Уравнения математической физики".
Задание: Привести к каноническому виду 5u_xx+6u_xy+u_yy+2xu_x+u_y+y-1=0.
L₀u(x,y)=5u_xx+6u_xy+u_yy
L₁u(x,y)=2xu_x+u_y+y-1
Я уже начал решать:
1) Определим тип уравнения: d=b²-ac=9-4=4 > 0 [$8658$] уравнение гиперболического типа
.....
.....
2) Определим семейство характеристик
.....
.....
Помогите пожалуйста найти [$958$] и [$627$] и решить до нахождения частных производных.
