Definition
tan(angle) = opposite / adjacent = sin(angle) / cos(angle)
Key Values
Exemplo Resolvido
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
Perguntas Frequentes
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.
