Data Source and Methodology
Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da fonti autorevoli in matematica trigonometrica.
The Formula Explained
\[ \sin(\theta) = \text{opposite} / \text{hypotenuse} \]
\[ \cos(\theta) = \text{adjacent} / \text{hypotenuse} \]
\[ \tan(\theta) = \sin(\theta) / \cos(\theta) \]
Glossary of Terms
- Angle: The measure in degrees for which trigonometric values are calculated.
- Sine: Ratio of the opposite side to the hypotenuse in a right triangle.
- Cosine: Ratio of the adjacent side to the hypotenuse in a right triangle.
- Tangent: Ratio of the sine to the cosine.
