If A+B=45^(@) , then (1+ tan A)(1+ tan B) =__________

If A+B=45^(@) , then (1+ tan A)(1+ tan B) =__________

If A + B = 45^@ , show that (1+tanA) (1+tanB) =2

If A+B=45^(0) and none of A and B is an odd multiple of (pi)/(2) ,prove that (1+tan A)(1+tan B)=2 and hence deduce that tan22(1)/(2)=sqrt(2)-1
