Question

sin2A/(1-cos2A)=cosA/sinA

Answer 1

Answer:

The results in an error

Answer 2

Step-by-step explanation:

sin2A / (1-cos2A)= cotA

2 sinA cos A/ Cot A = 1-cos 2A

2 sinA cosA*TanA = 1-cos2A

2 sinA cosA * sinA / cos A = 1-cos2A

2 sin A sinA = 1- cos2A

2 sin square A = 1-( 1- 2 sin square A)

2 sin square A = 1- 1 + 2 sin square A

2sin square A = 2 sin square A

Hence proved
