Answer 1

Answer:

Step-by-step explanation:

Sin 2A = 2 SinA . CosA

           = (2 SinA . Cos A) / 1

            = 2 SinA. Cos A / (cos^2 A + sin^2 A)

Dividing cos^2 A on both parts,

            = (2 SinA. Cos A/ Cos^2 A) / (cos ^A / cos ^ A + sin ^2 A / cos ^ A)  

            = 2 TanA / ( 1 + Tan^2 A)
