In summary follow the steps below in order to find the equation of the normal line. Find the equation of tangent and normal to the curve y x3 at 1 1. So we find equation of normal to the curve drawn at the point p4 1.
Y x 3.
Equation of a Normal Line in Cartesian Coordinates A straight line perpendicular to the tangent and passing through the point of tangency x0y0 is called the normal to the graph of the function y f x at this point Figure 2. Tangent plane and normal line. Y y 1 m x x 1 y 3 2 2 x p 6 Answer. Y 3x 2.
