Kalkulator Trigonometri – Hitung Sin Cos Tan & Segitiga Siku-Siku

Rumus & Metodologi Perhitungan

            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.

Panduan Penggunaan 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.

Pertanyaan yang Sering Diajukan (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.
