Tangent Table for certain values
| Degrees | Tangent values |
| 0° | 0 |
| 30° | ⅓√3 |
| 45° | 1 |
| 60° | √3 |
| 90° | ∞ (Infinity) |
| 180° | 0 |

| 360° | 0 |
Tangent periodicity starts at 180°. For tangents, apply below:
Tg (k.180◦ + α) = tg α
Tg (k.180◦ + α) = tg α
Example:
tg 750◦ = tg (2.360◦ + 30◦)
= tg (4.180◦ + 30◦)
= tg 30◦ = ⅓√3
tg 750◦ = tg 30◦ = 0.57735027
Tangent Formula
1. tg a◦ = x∕y → y = x tg a◦
2. tg(-a◦) = -tg a◦
3. tg (180◦ – a◦) = -tg a◦
4. tg (90◦ + a◦) = -cotg a◦
5. tg (180◦ + a◦) = tg a◦
6. tg (270◦ – a◦) = cotg a◦
7. tg (270◦ + a◦) = -cotg a◦
8. tg (360◦ – a◦) = -tg a◦
9. tg (360◦ – a◦) = tg a◦
2. tg(-a◦) = -tg a◦
3. tg (180◦ – a◦) = -tg a◦
4. tg (90◦ + a◦) = -cotg a◦
5. tg (180◦ + a◦) = tg a◦
6. tg (270◦ – a◦) = cotg a◦
7. tg (270◦ + a◦) = -cotg a◦
8. tg (360◦ – a◦) = -tg a◦
9. tg (360◦ – a◦) = tg a◦
