Let say we have 2D vector then Vector can be written as P ⃗= P x + P y, this 2D vector can also be written as (P x, P y ) in rectangular form. We know that in 2D, there is only measurement in X-axis and Y-axis(Length and breadth) so in 2D vector, For Example with the understanding of 2D, 3D and vector, now let us understand Vector in 2D and 3D Vector in 2D
Let us assume a vector A, shift the tail of the vector a to the origin of the coordinate system, then the head of the vector will be at some point let say (j, k) on the plane, then the point (j, k) is called as the coordinate of the vector P. We know that to represent a point P on a cartesian plane we write P (x, y), where x is the point on x- axis and y is the point on the y-axis, but for vectors, it is different to represent a vector on a plane. Now let us understand more about 2D and 3D,Ģ Dimensional which means the shape having both length and width, and 3D dimensional which means, the shape which has Length, breath, and height. For example, Force, Force has specific Quantity and direction so force can be called as vector quantity. Let us first start with the definition of vector, In mathematics, Vector is the Quantity that has both Direction and Magnitude. However, to enhance the usage of vectors in more realistic applications, it is necessary to explain vectors in terms of three-dimensional planes. In general, we learn to solve vectors in two dimensions. However, in the real world, events take place in three dimensions. Vectors are useful in our everyday lives.
