• Trigonometric Equations and Identities Sen x + cos x / sen x = 1 + 1 / tan x. cos x / cot x = sen x. Sen x / csc x + cos x / sec x = 1. tan x / sen x = sec x. sec y / tan y + cot y = sen y. csc x / cot x = sec x. sec y / tan y + cot y = sen y. (Repeated) csc x / cot x = sec x. (Repeated) • Simplification and Algebraic Manipulations 1 - sen x / cos x = cos x / (1 + sen x). • Derivatives and Calculus sen' z = (1 - cos² z) / csc² z. • Pythagorean and Fundamental Identities sec x (1 - sen² x) = cos x. • Product of Trigonometric Functions tan z · cos z · csc z = 1.
