Answer:
Proved
Step-by-step explanation:
To Prove: 
Proof:
Now: 
Therefore:

Applying these angle sum formula


Divide all through by 

=sin \alpha cos \beta + cos \alpha sin \beta/cos \alpha cos \beta/cos \alpha cos \beta- sin \alpha sin \beta/cos \alpha cos \beta
=sin \alpha/cos \alpha + sin \beta/cos \beta/1-tan \alpha tan \beta
=tan A + tan B/1-tan A tan B
