Enter vector A

A =

Enter vector B

B =   

Calculate the length (magnitude) of A

Rewrite the vector in terms of coordinates:

(a1, a2) = (-643, -928)

The formula for this is below:

||A|| = Square Root(a12 + a22)
||A|| = Square Root(-6432 + -9282)
||A|| = √413449 + 861184
||A|| = √1274633
||A|| = 1128.9964570361

How does the Vectors Calculator work?
Free Vectors Calculator - Given 2 vectors A and B, this calculates:
* Length (magnitude) of A = ||A||
* Length (magnitude) of B = ||B||
* Sum of A and B = A + B (addition)
* Difference of A and B = A - B (subtraction)
* Dot Product of vectors A and B = A x B
A ÷ B (division)
* Distance between A and B = AB
* Angle between A and B = θ
* Unit Vector U of A.
* Determines the relationship between A and B to see if they are orthogonal (perpendicular), same direction, or parallel (includes parallel planes).
* Cauchy-Schwarz Inequality
* The orthogonal projection of A on to B, projBA and and the vector component of A orthogonal to B → A - projBA
Also calculates the horizontal component and vertical component of a 2-D vector.
