WebDec 5, 2024 · Trigonometric ratios are the constant values for specific angles. Learn about trigonometric ratios like sin, cos, and tan, their Formulas, Solved Examples, and FAQs in this article. WebApr 6, 2024 · sec − 1(– x) = π– sec − 1x. cot − 1(– x) = π– cot − 1x. If we divide a plane into four quadrants, then all the trigonometric functions are positive in the first quadrant. In the third quadrant tan and cot is positive. In the 4th quadrant cos and sec positive. All the trigonometric identities are cyclic and repeat themselves.
