An online calculator to calculate the magitude and direction of a vector.
Let v be a vectors given in component form by
v = <a , b>
The magnitude || v || of vector v is given by
|| v || = sqrt(a 2 + b 2)
and the direction of vector v is angle t in standard position and in couterclockwise direction such that
tan(t) = v / u
How to use the calculator
1 - Enter the components of vector v as real numbers and press "enter". The magnitude || v || and direction IN DEGREES are displayed.
