त्रिकोणमिति के महत्वपूर्ण फॉर्मूला (Important Formula Of Trignometry)
Basic Formula of Trignomery
- sinθ = 1/cosecθ
- cosθ = 1/secθ
- tanθ = 1/cotθ
- cotθ = 1/tanθ
- secθ = 1/cosθ
- cosecθ = 1/sinθ
त्रिकोणमिति अनुपात (Trigonometric Ratio)
- sinθ = लम्ब/कर्ण
- cosθ = आधार/कर्ण
- tanθ = लम्ब/आधार
- cotθ = आधार /लम्ब
- secθ = कर्ण /आधार
- cosecθ = कर्ण /लम्ब
त्रिकोणमिति सम्बन्ध (Trigonometric Relation )
- sinθ.cosecθ = 1
- cosθ.secθ = 1
- tanθ.cotθ = 1
- tanθ = sinθ/cosθ
त्रिकोणमितीय सर्वसमिकाएँ (Trigonometric Identities)
- sin²θ + cos²θ = 1
- 1 + tan²θ = sec²θ
- 1 + cot²θ = cosec²θ
कोण योग और विभिन्न सर्वसमिकाये (Angle Sum And Difference Identities)
- sin(A+B) = sin A cos B + cos A sin B
- sin(A–B) = sin A cos B – cos A sin B
- cos(A+B) = cos A cos B – sin A sin B
- cos(A–B) = cos A cos B + sin A sin B
- tan( A+B) = (tan A + tan B)/(1–tan A tan B)
- tan( A–B) = (tan A – tan B)/(1+tan A tan B)
