1. The correct order of Ratios of Trigonometry are
Sin θ , Cos θ,Cot θ, Cosec θ, Sec θ, Tan θ
Sin θ , Cosec θ,Tan θ, Cos θ, Sec θ, Cot θ
Sin θ , Cos θ, Tan θ, Cosec θ, Sec θ, Cot θ
2. Tan θ =
P/B
H/B
B/P
3. Cos θ =
B/H
H/B
B/P
4. Cot θ =
HB
B/P
H/P
5. Cos 90° =
0
1
1/2
6. Sin 60° =
√/3
√3/2
√3/√2
7. Cosec 0° =
∞/2
Not Defined
√877
8. Cot 45° =
1
2
0
9. Sin θ =
Cot(90 - θ)
Cosec(90 - θ)
Cos(90 - θ)
10. Cot (90 - θ) =
Sec θ
Cosec θ
Tan θ
11. Cosec 80° =
Cot 10°
Not Known
Sec 10°
12. Cos^2 θ + Sin^2 θ =
0
2
1
13. 1 - Sec^2 θ =
Tan^2 θ + 1
Tan^2 θ +1
-Tan^2 θ
14. 1 =
Cosec^2 θ - Cot^2 θ
Cosec^2 θ + Cot^2 θ
Cot^2 θ - Cosec^2 θ
15. Sec θ =
1 / √(1 - Sin^2)
√(1 - Sin^2) / 2
√(1 - Sin^2)
