SUMMARY
The discussion focuses on calculating the magnitude and angle of a vector expressed as -25.3i - 1.2j. The correct angle is determined using the arctan function, with adjustments based on the signs of the vector components. Specifically, since both components are negative, 180 degrees is added to the arctan result of 2.72, yielding a final angle of 182.72 degrees. This method ensures accurate representation of the vector's direction in the Cartesian plane.
