Trigonometrie Rechner – Sinus, Cosinus, Tangens & Dreiecksrechner

Formeln und Berechnungsmethodik

            sin²(θ) + cos²(θ) = 1, \quad a² + b² = c²
          

Trigonometric ratios in right triangles: sin(θ) = Opposite/Hypotenuse, cos(θ) = Adjacent/Hypotenuse, tan(θ) = Opposite/Adjacent.

Anleitung: So verwenden Sie Trigonometry & Right Triangle Calculator

Select your preferred angle unit: Degrees (°) or Radians (rad).
Use the quick trigonometric evaluator or switch to the Right Triangle Solver tab.
Enter two known elements (e.g., two sides, or one side and an acute angle).
Inspect the dynamically rendered triangle diagram with exact side lengths, angles, perimeter, and area.

Häufig Gestellte Fragen (FAQ)

When should I use degrees versus radians?

Use degrees (°) for standard geometry, engineering, navigation, and construction. Use radians (rad) for calculus, periodic oscillations, and advanced physics.
