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

الصيغة

sin(θ) = Opposite / Hypotenuse

دليل خطوة بخطوة

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

أمثلة محلولة

الإدخال

Right triangle: hypotenuse 10, angle 30°

النتيجة

Opposite = 10×sin(30°) = 10×0.5 = 5; Adjacent = 10×cos(30°) = 8.66
