WebJul 25, 2024 · Normal Lines Given a vector and a point, there is a unique line parallel to that vector that passes through the point. In the context of surfaces, we have the gradient … WebTangents and normals are lines at a given point on a curve. A tangent runs parallel with the curve at the point whereas the normal is perpendicular to the curve. It follows that if the curve has gradient m, the tangent also has gradient m and the normal has gradient − 1 / m. See more on perpendicular straight lines.
