Answer 1

Answer:

that's the answer for your question

Answer 2

$\frac{cot \theta + cos \theta}{cot \theta - cos \theta} \\ \\ = \frac{ \frac{cos \theta + cos \theta sin \theta}{sin \theta} }{ \frac{cos \theta - cos \theta sin \theta}{sin \theta} } \\ \\ = \frac{cos \theta + cos \theta sin \theta}{cos \theta - cos \theta sin \theta} \\ \\ = \frac{1 + sin \theta}{1 - sin \theta} \\ \\ = \frac{cosec \theta + 1}{cosec \theta - 1}$
