The 2-norm of a Vector
Let
Another way to calculate the 2-norm is to take the 5.1 Inner Product Between Vectors using the following formula:
Remark. The two-norm is also known as the euclidean norm.
Remark. From this point on, the two norm will be denoted with the following notation:
Remark. There are many other vector-norms two consider. However, we will focus on the 2-norm as it is the most important when it comes to introductory linear algebra.
Remark. In Multivariable Calculus, the 2-norm of a Vector is also known as the magnitude.
