sin^2a/(1-sin^2a) = tan^2a
First, let's simplify the left side of the equation:
sin^2a / (1 - sin^2a) = sin^2a / cos^2a= (sin a / cos a)^2= tan^2a
Therefore, sin^2a / (1 - sin^2a) = tan^2a
sin^2a/(1-sin^2a) = tan^2a
First, let's simplify the left side of the equation:
sin^2a / (1 - sin^2a) = sin^2a / cos^2a
= (sin a / cos a)^2
= tan^2a
Therefore, sin^2a / (1 - sin^2a) = tan^2a
