Trigonometric Functions — Key Formulas
| Formula | Expression |
|---|---|
| Sine Function | sinθ = opposite/hypotenuse |
| Cosine Function | cosθ = adjacent/hypotenuse |
| Tangent Function | tanθ = sinθ/cosθ = opposite/adjacent |
| Pythagorean Identity | sin²θ + cos²θ = 1 |
| Double Angle: Sine | sin(2θ) = 2sinθ cosθ |
| Double Angle: Cosine | cos(2θ) = cos²θ − sin²θ |
| Double Angle: Tangent | tan(2θ) = 2tanθ/(1 − tan²θ) |
