cot A/2= siA /1-cosA

Answers

Answered by priyel

Step-by-step explanation:

$\large\bf \frac{cotA}{2} = \frac{sinA}{1-cosA} \\ \\ \tt \mapsto2sinA = \frac{sinA}{cosA} \times (1 - cos A) \\ \\ \tt \mapsto2sinAcosA = sinA - sinAcosA \\ \\ \tt \mapsto3sinAcosA = sinA \\ \\ \tt \mapsto \: sinA = 3cosA - 1$
