Formel
## Tangent Function ### Definition **tan(angle) = opposite / adjacent = sin(angle) / cos(angle)** ### Key Values | Angle | tan | |-------|-----| | 0° | 0 | | 30° | 1/√3 ≈ 0.5774 | | 45° | 1 | | 60° | √3 ≈ 1.7321 | | 90° | undefined |
Lösungsbeispiel
Calculate tan(45°).
- 01tan(45°) = 1
- 02sin(45°) = √2/2 ≈ 0.7071
- 03cos(45°) = √2/2 ≈ 0.7071
- 04tan = sin/cos = 0.7071/0.7071 = 1
Häufig Gestellte Fragen
What is the tangent function?
Tangent is the ratio of sine to cosine, or equivalently, the ratio of the opposite side to the adjacent side in a right triangle.
Why is tan(90°) undefined?
At 90°, cosine equals zero, and division by zero is undefined. The tangent function approaches infinity as the angle approaches 90°.
What is the period of tangent?
Tangent has a period of 180° (pi radians), which is half the period of sine and cosine.
