- 7. the ration of adjacent side and hypotenuse.
- 8. value of tan 30
- 9. value of cosec 60
Down
- 1. If cos(α + β) = 0, then sin(α – β) can be reduced to:
- 2. sin 2A = 2 sin A is true when A
- 3. If sin A = 1/2 , then the value of cot A is
- 6. the ratio of opposite side and hypotenuse.
- 8. value of cos 60
