Trigonometric ratios (SOH-CAH-TOA) relate the angles and sides of right triangles. They are fundamental in geometry, physics, engineering, and navigation.

Công thức

sin(θ) = Opposite / Hypotenuse

Hướng dẫn từng bước

  1. 1sin(θ) = Opposite / Hypotenuse
  2. 2cos(θ) = Adjacent / Hypotenuse
  3. 3tan(θ) = Opposite / Adjacent
  4. 4Inverse: θ = arcsin(O/H) to find angle from ratio

Ví dụ có lời giải

đầu vào
Right triangle: hypotenuse 10, angle 30°
Kết quả
Opposite = 10×sin(30°) = 10×0.5 = 5; Adjacent = 10×cos(30°) = 8.66
