In geometry, a normal is an object (e.g. a line, ray, or vector) that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the line perpendicular to the tangent line to the curve at the point. A normal vector of length one is called a unit normal vector.
Normal is a line perpendicular to the tangent at the point of contact. The equation of the talent at the point (x 1, y 1) is of the form (y - y 1) = m (x - x 1 ), and the equation of a normal passing through this same point is (y - y 1) = -1/m. (x - x 1 ).
A normal distribution is the bell-shaped frequency distribution curve of a continuous random variable. Visit BYJU’S to learn its formula, curve, table, standard deviation with solved examples. Login
The equation of the normal at the point (2, 8) is therefore: y - 8 = -1/12 (x - 2) hence the equation of the normal at (2,8) is 12y + x = 98 . Tangents and Normals A-Level maths revision section looking at tangents and normals within calculus including: definitions, examples and formulas.
There are different kind of contexts you use term normal in mathematics. You often use perpendicular in case of two or three dimensional geometry, and in hi-dimensional spaces (e.g. infinite-dimensional) a term orthogonal is more common.
Definition. At every given position along the curve, a normal is a straight line that cuts through the curve at a certain point and runs in a direction that is perpendicular to the tangent at a certain point.
Definition of. Normal. more ... At right angles to, going directly away from. For a curve imagine a line just touching and matching the slope there (called a "tangent") and draw a line at right angles to it. Example: a circle's diameter is always normal to its circumference.
Normal. The math word 'normal' means to be at right angles, or meeting at 90° In the figure below the line JK is normal to AB. The usual way of saying this is that JK is perpendicular to AB.

Normal. to a curve (or surface) at a point of it. A straight line passing through the point and perpendicular to the tangent (or tangent plane) of the curve (or surface) at this point. A smooth plane curve has at every point a unique normal situated in the plane of the curve.
