If `A+B=pi/4`, then `(tan A + 1) (tan B+1)` equals

If A+B= pi/4 , then (1+tan A) (1+tanB) is equal

If A-B=pi/4, then (1+tan A)(1-tan B) is equal to 2 b.1 c.0 d.3

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

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

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

If y = (1 + tan A) (1 - tan B), where A -B=pi/4 then (y+ 1)^(y + 1) is equal to

if A + B+ C= pi/2 ,show that tan A tan B + tan B tan C+ tan C tan A = 1

If sin(A + B) = 1 and 2 sin (A - B) = 1, where 0 lt A, B lt pi/2 then what is tan A:tan B equal to?

If y = (1 + tan A) (1 - tan B), where A -B=pi/4 then (y+ 1)^(y + 1) is equal to ............ A) 9 B) 4 C) 27 D) 81
