Introduction to learn unit vector:
Physical quantities are divided into two groups, i.e. scalars and vectors. Scalar quantities are those having only magnitude like work done, length, mass etc. Vector quantities are those having magnitude as well as direction like displacement, force, acceleration etc.
I like to share this Vectors Math with you all through my article.
Learn Unit Vectors:
Vectors are symbolically denoted by a line segment with a direction. The length of the line segments gives the magnitude and the direction of the arrow denotes the direction of the vector.
A vector whose magnitude is one unit is called a unit vector, a unit vector is represented with a letter that names the vector with a cap. The cap in the letter is the indication that it is a vector.
Denoted by â, read as ‘a cap’. Thus, │â│=1.
If│ │ represents the magnitude of a vector, then │â │=1.
The vectors are extensively used in linear algebra. The variable in linear algebra exists in two dimensional x or y axis or y and z axis. The vector not only gives the magnitude of the variable, they also give the direction of the variables.
Vectors are usually defined by the corresponding coordinates. A unit vector in a two dimensional space will have two co-ordinates and a vector in a three dimensional space will have three co-ordinates. A vector with more than one co-ordinate will have the magnitude equal to the square root of the sum of the squares of the co-ordinates.
To find the magnitude of the vectorV (1, 3), we add the squares of the co-ordinates 1 and 3.
This is equal to 10. Now the square root of 10 is greater than 1. ThereforeV (1, 3) is not a unit vector. The basic unit vectors for the three dimensions individually are represented as
X (1, 0, 0), y (0, 1, 0) and z (0, 0, 1)
Understanding cbse commerce syllabus is always challenging for me but thanks to all math help websites to help me out.
Conclusion to Unit Vectors:
Vectors are physical quantities that have a direction and magnitude. Unit vectors have magnitude equal to one unit. Vectors in two dimensional and three dimensional spaces are represented by the co-ordinate values. Vectors are an important part of linear algebra studies.
