1- cos A​

Answer 1

Answer:

hey brother , this is math's question.

you put your question in wrong subject.

sin A

= cosec A + cot A.

1- cos A

Answer 2

$\frac{sinA}{1 - cosA} \\ = \frac{sinA}{1 - cosA} \times \frac{1 + cosA}{1 + cosA} \\ = \frac{sinA(1 + cosA)}{ {sin}^{2} A} \\ = \frac{1 + cosA}{sinA} \\ = cosecA + cotA$
