Formula Sheet — Trigonometric Functions

Important formulas and equations from Trigonometric Functions for J&K CET Mathematics.

Formulas — Trigonometric Functions

Angle Measurement & Basic Conversions

π radians = 180°
1 radian = (180/π)° ≈ 57.3°
1 degree = (π/180) radians
Arc length = rθ

Fundamental Trigonometric Functions

sin θ = opposite/hypotenuse
cos θ = adjacent/hypotenuse
tan θ = opposite/adjacent = sin θ/cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ

Standard Angle Values

Fundamental Identities

sin²θ + cos²θ = 1
1 + tan²θ = sec²θ
1 + cot²θ = cosec²θ
tan θ = sin θ/cos θ
cot θ = cos θ/sin θ
