Consider the following second-order partial differential equation : *,), z>0,y > 0. (G) 1. The equation (F) is : a) Hyperbolic Equation b) Parabolic Equation e) Elliptic Equation d) None of the nhove 2. The characteristics equations corresponding to (G) are: a) = and =-2. b) =3 and = 4. e)2 =. d) None of the aboe. 3. Using the change of variable a = r + and 8= y, the canonical form of (G) is: m) Has +a =0. b) uga + M, = 0. c) ugg - Jus = 0. d) None of the above. 4. Let f nnd g two arbitrary real valued funetions. A general solution of (G) is: a) u(2, y) = f(x² +y²) + y²g(x² + g²). b}u(x, y) = f(x) +r*g(r* +y®). e) u(x,y) = {(x) +²g(x² + y?). d) None of the above.
