Tan 2A Formula – Proof and Examples – Mathemerize
WEBHere you will learn what is the formula of tan 2A in terms of tan with proof and examples based on it. Let’s begin – Tan 2A Formula : The formula of tan 2A is \(2 tan A\over 1 – tan^2 A\) Proof : We have, tan (A + B) = \(tan A + tan B\over 1 – tan A tan B\) Replacing B by A, \(\implies\) tan 2A = \(tan A + tan A\over 1 – tan A tan A\)
