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

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

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

If A +B = 45 ^(@), show that tan A + tan B + tan A tan B =1. Hence or otherwise, express tan 22 ^(@) 30' in surd form.

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

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=(3pi)/(4) , that show that (1- tan A) (1+tan B)=2

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

If A+B = 90^@ , show that tan A + tan B = (cosec^2B)/sqrt(cosec^2B-1)
