Dear
Aspirants, We are sharing with you Trigonometry Formulas PDF Study Material. Trigonometry
Formula PDF
is very helpful for the upcoming exams like SSC CGL, CHSL, etc.,
Trigonometry Formula List PDF contains all the formulas and also very
from this sscnotes.com, Trigonometry Formulas PDF in Hindi
also provided.

In Mathematics, Trigonometry is the very most important subject/section to
learn. Trigonometry is explain about triangles and ‘Trigon’ means triangle and
‘metry’ means measurement.

### Trigonometry formula

1. Sin θ = 1 / cosec θ

2. cosec θ = 1 / Sin θ

3. cos θ = 1 / sec θ

4. sec θ = 1/ cos θ

5. sin θ.cosec θ = 1

6. cos θ.sec θ = 1

7. tan θ.cot θ = 1

8. tan θ = sin θ / cos θ

9. cot θ = cos θ / sin θ

10. tan θ = 1 / cot θ

11. cot θ= 1 / tan θ

### Pythagorean Identity Formula

1. sin2 θ + cos2 θ = 1

2. sec2 θ = tan2 θ
+ 1

3. cosec2 θ =1 + cot2θ

### Trigonometric Angle and Measurements

1. sin (90° – θ) = cos θ

2. cos (90° – θ) = sin θ

3. tan (90° – θ) = cot θ

4. cosec (90° – θ) = sec θ

5. sec (90° – θ) = cosec θ

6. cot (90° – θ) = tan θ

7. sin (90° + θ) = cos θ

8. cos (90° + θ) = – sin θ

9. tan (90° + θ) = – cot θ

10. cosec (90° + θ) = sec θ

11. sec (90° + θ) = – cosec θ

12. cot (90° + θ) = – tan θ

13. sin (180° – θ) = sin θ

14. cos (180° – θ) = – cos θ

15. tan (180° – θ) = – tan θ

16. cosec (180° – θ) = cosec θ

17. sec (180° – θ) = – sec θ

18. cot (180° – θ) =  – cot θ

19. sin (180° + θ) = – sin θ

20. cos (180° + θ) = – cos θ

21. tan (180° + θ) = tan θ

22. cosec (180° + θ) = – cosec θ

23. sec (180° + θ) = – sec θ

24. cot (180° + θ) =  cot θ

25. sin (360° –  θ) = – sin θ

26. cos (360° –  θ) = cos θ

27. tan (360° –  θ= – tan θ

28. cosec (360° –  θ) = – cosec θ

29. sec (360° –  θ) = sec θ

30. cot (360° –  θ= – cot θ

31. sin (360° +  θ) = sin θ

32. cos (360° +  θ) = cos θ

33. tan (360° +  θ= tan θ

34. cosec (360° +  θ) = cosec θ

35. sec (360° +  θ) = sec θ

36. cot (360° +  θ= cot θ
