  1. The magnitude of each vector is found by taking the square root of the square of each component.

    ||(2,6)|| = sqrt(2^2 + 6^2)

    It is usually written as double bars.

    The vector can also be expressed as the sum of scalar components multiplied by unit vectors. With i = (1, 0) and j = (0, 1), then (2, 6) = 2i + 6j.
