Question

if A is a vector which unit m^2 then what will be the unit of delta.(delta*A)​

Answer 1

Explanation:

In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) of length 1. A unit vector is often denoted by a lowercase letter with a circumflex, or "hat", as in {\displaystyle {\hat {\mathbf {v} }}} {\hat {{\mathbf {v}}}} (pronounced "v-hat").[1][2]

The term direction vector is used to describe a unit vector being used to represent spatial direction, and such quantities are commonly denoted as d; 2D spatial directions represented this way are numerically equivalent to points on the unit circle. The same construct is used to specify spatial directions in 3D, which are equivalent to a point on the unit sphere.
