Prove that tan(45°+ A) - tan(45°- A)/tan(45°+ A) + tan(45°- A) = 1/sin2A

Prove that tan(45°+ A) - tan(45°- A)/tan(45°+ A) + tan(45°- A) = 1

1.	Prove that tan(45°+ A) - tan(45°- A)/tan(45°+ A) + tan(45°- A) = 1/sin2A
Answer» Hence Proved that tan(45°+A) - tan(45°- A) /tan(45°+A) + tan(45°-A) = 1/sin2A To prove the above equation, we will use trigonometric identities and value of tan45°.
