三角函数计算器 – 正弦余弦正切 & 直角三角形勾股定理求解

计算公式与算法逻辑

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

Trigonometry & Right Triangle Calculator使用指南与操作步骤

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