(i) यदि ` A-B = pi/4,` तो सिद्ध कीजिए कि ` (1 + tan A)(1-tanB)=2`

If A-B = pi/4 , then (1+tanA)(1-tanB)=

If A-B = pi/4 , then (1+tanA)(1-tanB)=

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

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

If A+B=pi/4 , then (1+tanA)(1+tanB)=

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

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

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

If A+B=pi/4 show that (1+tanA)(1+tanB)=2
