This cheat sheet mainly focuses on trigonometric identities and inequalities involving three angles, whose sum is 180° (or π radians).Ī basic knowledge of trigonometric ratios and related identities is a must for understanding these conditional trigonometric identities. It covers a special case of trigonometric identities, in which a particular relation between the angles involved is known. This cheat sheet covers the high school math concept – Conditional Trigonometric Identities.
