Question

find the value of :( 1+ cot²θ) (1+ cos θ) (1-cosθ)
please help fast!! ​

Answer 1

Answer:

cosec Q -sinQ

Step-by-step explanation:

here Q represents tetta

Answer 2

$(1 + { \cot}^{2} θ)(1 + cosθ)(1 - cosθ) \\ =( cosec {}^{2} θ)(1 - cos {}^{2} θ) \\ = (cosec {}^{2} θ)(sin {}^{2} θ) \: \: \: \: \: \: \: \: \\ = cosec {}^{2}θ \times \frac{1}{cosec {}^{2} θ} \: \: \: \: \:$

$\frac{cosec {}^{2}θ }{cosec {}^{2} θ} = 1$

The value is 1.
