## Trigonometry Formulas for Class 11th and 12th

### 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

## Mathematics Formula Trigonometry

1. Sin²θ +cos²θ=1
2. 1+tan²θ= sec²θ
3. 1+cot²θ= cosec²θ
4. sin(A+B)= sinA.cosB+cosA.sinB
5. sin(A-B)= sinA.cosB-cosA.sinB
6. cos(A+B)= cosA.cosB-sinA.sinB
7. cos(A-B)= cosA.cosB+sinA.sinB
8. tan(A+B)= (tanA+tanB)/(1-tanA.tanB)
9. tan(A-B)= (tanA-tanB)/(1+tanA.tanB)
10. sin²A= 2sinA.cosA
11. cos²A= cos²A-sin²A=2cos²A-1=1-2sin²A
12. tan²A= 2tanA/(1-tan²A)
