Question

force in field is phi(x,y,z) has direction gradient of phi . calculate grad phi

phi(x,y,z)=((x-1)^2) - ((y+1)^2) force in field is phi(x,y,z) has direction gradient of phi . calculate grad phi

phi(x,y,z)=((x-1)^2) - ((y+1)^2) @Mathematics

Answer 1

grad phi is just the partial differentials right?

Answer 2

x' = 2(x+1)
y' = 2(2+1)
z' = 0
