# Magnitude and Direction of a Vector - Calculator

An online calculator to calculate the magnitude and direction of a vector from it components.
Let v be a vector given in component form by
## Use of the calculator to Calculate Magnitude and Direction1 - Enter the components v_{1} and v_{2} of vector v as real numbers and press "Calculate Magnitude and Direction". The outputs are the magnitude || v || and direction θ in degrees of vector v.
## Use the calculator of Magnitude and Direction to Answer the Questions- Use the calculator to find the direction of the vectors u = < - 2 , 3 > and v = < - 4 , 6 >. Why are they equal?
- Find the direction of the vectors u = < 2 , 5 > and v = < - 2 , - 5 >. Why is the difference between the two directions equal to 180°?
- Use the calculator to find the direction of the vectors u = < 2 , 1 > and v = < 1 , 2 >. Why is the sum of the two directions equal to 90°? Find other pairs of vectors whose directions add up to 90°
