no it is not correct
tan( A+B) = (TanA+TanB)/1-tanAtanB
Let A = 30°and B= 60°
so
tan 90°= (tan30°+tan60°)/1-tan60°tan30°
tan 60°= √3,tan 30° =1/√3
putting value we get tan 90°=undetermined form
which is correct
tan(A+B)= tanA+tanB only possible if A any one of A and B is 0°
tan( A+B) = (TanA+TanB)/1-tanAtanB
Let A = 30°and B= 60°
so
tan 90°= (tan30°+tan60°)/1-tan60°tan30°
tan 60°= √3,tan 30° =1/√3

no it is not possible
let take A=60° and B=30°
tan(60+30)= 90
tan (90)= not define
tan60=√3 and tan30=1/√3
√3×1/√3=3. so it not possible
