[15.-(a)" यदि "A+B=(pi)/(4)" है तो स्धि कीजिए कि "],[(1+tan A)(1+tan B)=2]

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

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

AB = (pi) / (4), then (1 + tan A) (1-tan B) =

IF A + B = (pi)/(4) then ( tan A +1) ( tan B+1) equals

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=(pi)/(4) then (1+tan A)(1-tan B)=

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 (1+tan A)(1-tan B) is equal to 2 b.1 c.0 d.3
