In mathematics, there are a total of six different types of trigonometric functions: sin, cos, sec, cosec, tan, and cot . Download free Pdf and Learn all the Trigonometry Formulas, identities, functions, and examples for better preparation. Check all basic and advanced trigonometry formulas based on trigonometric ratios (sin, cos, tan) and 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. Similarly, inverse of all the trigonometry function is angle. Note : Here angle is measured in radians, not degrees. Davneet Singh has done his B.Tech from Indian Institute of Technology, Kanpur. He has been teaching from the past 14 years.
