a vector that has a magnitude of 1 and represents direction without regard to scale
- A unit vector is often employed in mathematics to define orthonormal bases and to describe geometric transformations.
单位向量常用于数学中定义正交基和描述几何变换。
- Unit vectors are essential in vector calculus for expressing the gradient, divergence, and curl of vector fields.
单位向量在向量微积分中对于表达向量场的梯度、散度和旋度至关重要。
- The electric field at a point due to a charged particle can be expressed as a vector quantity using a unit vector to represent direction.
由于带电粒子在某一点产生的电场可以表示为使用单位向量表示方向的向量量。
- To describe the direction of a force in physics, we often use a unit vector representing the direction without considering the magnitude.
在物理学中描述力的方向时，我们经常使用一个单位向量来表示方向而不考虑大小。
