One of the simplest and most basic formulas in Trigonometry provides the measure of an arc in terms of the radius of the circle, N, and the arc’s central angle θ, expressed in radians.
This book covers the major topics within the study of trigonometry, including vectors and their applications. At the University of Minnesota, this material is 75% of the PreCalculus II course, with the remaining 25% of that course covering algebraic topics which are included in a separate text.

Fundamental trig identity. cos(. (cos x)2 + (sin x)2 = 1. 1 + (tan x)2 = (sec x)2 (cot x)2 + 1 = (cosec x)2.
Reciprocal Identities: These identities define the relationships between each trigonometric function and its reciprocal. cscθ = 1/sinθ. secθ = 1/cosθ. cotθ = 1/tanθ. Quotient Identities: These identities show that tangent and cotangent are ratios of sine and cosine. tanθ = sinθ/cosθ. cotθ = cosθ/sinθ.
Trigonometry Resources: Identities and Formulas. In mathematics, there are common shorthand notations to reduce the number of parentheses used. Below are a few examples of these shorthands and their corresponding mathematical interpretations to keep in mind.
