find the gradient field for the potential function fxyzx cos
find the gradient field for the potential function f(x,y,z)=x cos (y/z)
Solution
E(x,y,z) = - (V/x + V/y +V/z)
E(x,y,z) = - (cos (y/z) + (x/z)* (-sin(y/z)) - x*y* (-sin(y/z))/(z^2))

E(x,y,z) = - (V/x + V/y +V/z)
E(x,y,z) = - (cos (y/z) + (x/z)* (-sin(y/z)) - x*y* (-sin(y/z))/(z^2))
