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

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

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

If A+B=(pi)/(4), prove that: (1+tan A)(1+tan B)=2(cot A-1)(cot B-1)=2

If A+B=pi/4 ,prove that (1+tan A)(1+tan B)=2

If A+B=45^(@) , then prove that (i) (1+ tan A) (1+ tan B) =2 (ii) (cot A-1) (cot B-1)=2

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

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

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