Question 5

Multiple Choice

The five-point approximation of the Laplacian is


A) [u(x+h,y) +u(x,y+h) +u(x−h,y) +u(x,y+h) −4u(x,y) ][ u ( x + h , y ) + u ( x , y + h ) + u ( x - h , y ) + u ( x , y + h ) - 4 u ( x , y ) ]
B) [u(x+h,y) +u(x,y+h) +u(x−h,y) +u(x,y+h) −2u(x,y) ][ u ( x + h , y ) + u ( x , y + h ) + u ( x - h , y ) + u ( x , y + h ) - 2 u ( x , y ) ]
C) [u(x+h,y) +u(x,y+h) +u(x−h,y) +u(x,y+h) −4u(x,y) ]/h[ u ( x + h , y ) + u ( x , y + h ) + u ( x - h , y ) + u ( x , y + h ) - 4 u ( x , y ) ] / h
D) [u(x+h,y) +u(x,y+h) +u(x−h,y) +u(x,y+h) −4u(x,y) ]/h2[ u ( x + h , y ) + u ( x , y + h ) + u ( x - h , y ) + u ( x , y + h ) - 4 u ( x , y ) ] / h ^ { 2 }
E) [u(x+h,y) +u(x,y+h) +u(x−h,y) +u(x,y+h) −2u(x,y) ]/h2[ u ( x + h , y ) + u ( x , y + h ) + u ( x - h , y ) + u ( x , y + h ) - 2 u ( x , y ) ] / h ^ { 2 }
