Question

cosec A ( 1-Cos A) (Cosec A + Cot A)= 1
give correct answer....

Answer 1

Step-by-step explanation:

cosecA (1-cosA) (cosecA + cotA)

1/sinA (1-cosA) (1/sinA + cosA/sinA)

1/sinA (1-cosA) (1+cosA / sinA)

1/sinA (1-cosA) (1+cosA) × 1/sinA

1/sin^2 × (1-cosA) (1+cosA)

1-cos^2A/ sin^2 A

sin^2A / sin^2A
