Answer: For solving this questions we need to rationalize the denominator. Given sinA = cosA We know that sin 45 = cos45 = 1/ root2 Hence, A = 45 degrees Therefore, 2tan 2 A + sin 2 A - 1 = 2tan 2 45 o + sin 2 45 Jul 17, 2019 ... prove sinA+cosA/(sinA-cosA) + sinA-cosA/(sinA+cosA)=1/(sin2A-cos2A)=2/(1-2cos2A)=2sec2A/(tan2A-1).
