WebTo find the normal vector to this surface, we take the gradient of the equation and convert it to spherical coordinates: ∇ ( x 2 + y 2 − z 2) = < 2 x, 2 y, − 2 z > = 2 ⋅ cone ( r, − θ, ϕ) Is this correct? Although it may be correct, there is some part of my brain that doesn't fully grasp what I'm doing here. Web6. It follows from the general definition of the gradient as where p is a point in space and v a vector in the tangent space. The summation is over the basis vectors of the tangent …
