Key Concepts

Basis Vectors

Basis vectors, typically denoted by i and j in two-dimensional space, are standard unit vectors that point in the direction of the coordinate axes. Any vector in the plane can be expressed as a linear combination of these unit vectors, which provides a clear and standardized way to represent and manipulate vectors in mathematical operations.

Component Form of a Vector

Vectors in a plane can be expressed using their horizontal and vertical components. This form, written as a combination of the unit vectors in the x-direction and the y-direction, shows how the vector's magnitude is distributed along the axes. It simplifies vector operations like addition and subtraction by working with individual components.

Vector Subtraction

This concept involves finding the difference between two points to determine the displacement vector. In coordinate geometry, subtracting the coordinates of the initial point from the coordinates of the terminal point yields the components of the vector, which effectively represents how far and in what direction one point is from the other.
