In ΔABC, m∠C = 90 and m∠A = m∠B,
(1) Is cosA = cosB?
(2) Is tanA = tanB?
(3) Will the other trigonometric ratios of ∠A and ∠B be equal?
(1) yes, because the side AB and BC will be equal by property of triangle and therefore all the trigonometric ratios of these two angles will always be equal.
(2) yes, because the side AB and BC will be equal by property of triangle and therefore all the trigonometric ratios of these two angles will always be equal.

, verify that tan2θ – sin2θ = tan2θ
cos2A – sin2A.
