" 13.If "A+B=45^(@)" ,Prove that "(1+Tan A)(1+TanB)=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+tanA)(1+tanB)=2.

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

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

If A+B=pi/4 , prove that: (1+tanA)(1+tanB)=2

If A-B=pi/4 , then prove that: (1+tanA)(1-tanB)=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^(@) , then (1+ tan A)(1+ tan B) =__________

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