How to find the direction of the vector

The video tutorial explains how to calculate the magnitude and direction of a vector. It begins with finding the magnitude using the square root of the sum of the squares of the vector components. The tutorial then moves on to determining the direction by calculating the tangent of the angle, using the inverse tangent function to find the angle in degrees. The example provided results in a magnitude of 6√2 and a direction of -45 degrees.
