Question 231

Multiple Choice

Find the potential function f for the field F.
- F=sec2xsin2yi+2tanxsinycosyj+8z7k\mathbf { F } = \sec ^ { 2 } x \sin ^ { 2 } y \mathbf { i } + 2 \tan x \sin y \cos y \mathbf { j } + 8 z ^ { 7 } \mathbf { k }


A) f(x,y,z) =secxsin2y+z+Cf ( x , y , z ) = \sec x \sin ^ { 2 } y + z + C
B) f(x,y,z) =tanxsin2y+z8+Cf ( x , y , z ) = \tan x \sin ^ { 2 } y + z ^ { 8 } + C
C) f(x,y,z) =secxsin2y+z8+Cf ( x , y , z ) = \sec x \sin ^ { 2 } y + z ^ { 8 } + C
D) f(x,y,z) =secxsin2y+z8+Cf ( x , y , z ) = - \sec x \sin ^ { 2 } y + z ^ { 8 } + C
