Trigonometric Functions and Equations

In this video, Amal Kumar explains how to solve trigonometric equations using single ratios, focusing on secondary trigonometric ratios. The video covers two main problems: solving cosecant theta equals 2 and cot square x equals 3, both within the range of 0 to 2 pi. The instructor guides through identifying the correct quadrants, finding acute angles, and using calculators or special triangles to find solutions. The video emphasizes the importance of converting reciprocal ratios to primary trigonometric ratios for easier calculation.
