Be careful when calculating the angle of a vector

The video tutorial explains how to find the angle of a vector using trigonometric functions, specifically focusing on the tangent and its inverse. It highlights common mistakes students make when using calculators to find angles and clarifies the concept of reference angles. The tutorial also discusses how angles are interpreted in different quadrants and addresses the limitations of calculators in providing accurate angle measurements. The importance of understanding reference angles and performing manual calculations to verify results is emphasized.
