" Q1.If "A+B=45^(@)" ,then find "(1+tan A)(1+tan B)

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=135^(@) then (1-tan A)(1-tan B)=

If A+B=45^(@), then the value of (1+tan A)(1+tan B) is

if A+B=45^@ find the value of (1+tan A)(1+ tan B)

If A + B = 45^(@) , then find the value of (1+tan A)(1+ tan B)

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

If A+B=45^(@) then prove that (1+tan A)(1+tan B)=2. On the basis of the result obtained prove that tan22.5^(0)=sqrt(2)-1

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

If A+B=45^(@)," show that "(1+tan A) (1+tan B)=2 and hence deduce the value of tan"" 22""1^(@)/2 .
