The angle of direction of a vector refers to the anti-clockwise angle it forms with the positive x-axis. In order to determine this, you need to compute the arctangent of the ratio of the vector's y-coordinate to its x-coordinate (using the atan2(y, x) function). It's crucial to accurately determine the quadrant to prevent mistaken or negative angles.
