Trigonometry — Key Formulas
| Formula | Expression |
|---|---|
| The 3 main ratios | sin θ = opposite/hypotenuse · cos θ = adjacent/hypotenuse · tan θ = opposite/adjacent |
| Reciprocals | cosec θ = 1/sin θ · sec θ = 1/cos θ · cot θ = 1/tan θ |
| Quotient relations | tan θ = sin θ / cos θ · cot θ = cos θ / sin θ |
| The 3 identities | sin²θ + cos²θ = 1 · 1 + tan²θ = sec²θ · 1 + cot²θ = cosec²θ |
| Standard values of sin | sin 0°=0, sin 30°=1/2, sin 45°=1/√2, sin 60°=√3/2, sin 90°=1 |
| Standard values of cos | cos 0°=1, cos 30°=√3/2, cos 45°=1/√2, cos 60°=1/2, cos 90°=0 |
