Match the equation with its type. 1. \( z_{xx} + z_{yy} = 0 \) 2. \( z_{t} = \alpha z_{xx} \) 3. \( z_{tt} = c^{2}z_{xx} \) P. Parabolic Q. Elliptic R. Hyperbolic
Answer: A
The discriminant \( B^{2} - 4AC \) is \( -4 \), zero and \( 4c^{2} \) respectively. Negative gives elliptic, with data round a closed boundary; zero gives parabolic, marching forward from an initial state; positive gives hyperbolic, carrying disturbances along characteristics at finite speed
