Nazrul,. One way to approach this problem is to use sin2A = 1 - cos2A and hence write. Prove that: (cosA - sinA + 1) / (cosA + sinA +1) = (1 - sinA) / cosA. Answer: For solving this questions we need to rationalize the denominator. Show that 1+sin2Acos2A=cosA+sinAcosA−sinA=cot(π4−A). Solve for a variable, factor, expand, evaluate fractions, linear equations, quadratic equations, inequalities, systems of equations, matrices. cos 2 A = sin A . tan A ( G . P ) = sin A . sin A cos A cos 3 A = sin 2 A ⇒ cos 3 A sin 2 A = 1 → ( 1 ) cos 2 A sin 2 A . Oct 28, 2013 ... ⇒ 2sinA cosA = 3/4 ∴ sinA cosA = 3/8 → (1) (sinA + cosA)2 = (sinA – cosA)2 + 4sinA cosA = (1/2)2 + 4(3/8) = (1/4) + (3/2) = 7/4 (sinA + ...
