Question

Pls ans this. I will mark brainlist ​

Answer 1

Answer:

2

Step-by-step explanation:

Square on both sides

(cotθ + 1/cotθ)² = 2²

cot²θ + 2 + 1/cot²θ = 4       ( [a+b]² = a² + 2ab + b²)

cot²θ + 1/cot²θ = 2

Answer 2

Answer:

$({cota + \frac{1}{cota} })^{2} = {2}^{2} = 4 \\ {cot}^{2}a + 2 \times cota \times \frac{1}{cota } + \frac{1}{ {cot}^{2} a} = 4 \\ {cot}^{2} a + 2 + \frac{1}{ {cot}^{2}a } = 4 \\ {cot}^{2} + \frac{1}{ {cot}^{2} a} = 2$ (AAAA ki) jagah per tetha Rakh dena ok
