can u please clarifie this doubt for me

the statement is true Using tan(A-B) = (tanA - tanB)/(1+tanAtanB) RS = tan(x-6π) = (tanx - tan 6π)/(1 + tanxtan 6π) but 6π is coterminal with 2π (6π is 3 rotations, and 2π is one rotation so tan 6π = tan 2π = 0 = (tanx - 0)/(1+ ) = tanx = LS so the statem...
