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)
