Learn how to determine the magnitude and direction of a vector. The magnitude of a vector is the length of the vector. The magnitude of a vector is obtained by taking the square root of the sum of the squares of the components of the vector. The direction of a vector is obtained by taking the tan inverse of the ratio of the j component and the i component. • #trigonometry#vectors • #vectors
