Given the identity [sin(2a)/1 + cos(2a)]=tan(a)/1 prove the identity by following the implied steps and starting with the left side: sin(2a)/1 + cos(2a) 1). Substitute double-angle formulas into the numerator and denominator: 2). Simplify coefficients in the numerator and denominator: 3). Reduce out common factors: 4). Rewrite as the right side of the equation:
