Question

If sinθ = 1/2 write the value of (3cot^2θ +3).

Answer 1

Answer: 12

1. Step-by-step explanation:
2. for sin  theta to be 1/2, theta = 30°
3. now we know that theta = 30 °
4. (3 cot ^2*30° +3)
5. we know that cot 30° = √3
6. [3*(√3)^2+3]
7. [3*3+3]   ...(because (√3)^2 = 3)
8. (9+3)
9. 12
