Trigonometr

This topic covers the skill of calculating angles from given trigonometric ratios using inverse trigonometric functions, expressed in negative one notation (such as \( \cos^{-1} \), \( \tan^{-1} \), etc.). Each problem provides a ratio for a trigonometric function (cosine or tangent) and asks students to find the corresponding angle utilizing the inverse of that function. The multiple-choice format presents variations on how to apply inverse trigonometric functions and manipulate expressions to calculate angles correctly. Such practice is instrumental in deepening understanding of trigonometry fundamentals.
