Mastering trigonometry becomes much easier when you have all the essential formulas in one place. In this article, we present the Trigonometry Formulas List with Examples, covering everything from basic ratios to advanced identities. Trigonometric identities are equations involving trigonometric functions that hold true for all values of the variables within their domains. There are many such identities, either involving the sides of a right-angled triangle, its angle, or both. Below is the Trigonometry Formulas List that covers basic identities, reciprocal, ratio formulas , sum/difference, and more, essential for exams and quick reference. In Trigonometry , different types of problems can be solved using trigonometry formulas . These problems may include trigonometric ratios (sin, cos, tan, sec, cosec and cot), Pythagorean identities, product identities, etc.
