[" If "y=(1+tan A)(1-tan B)" where "],[A-B=(pi)/(4)" then the value of "(y+1)^(y+1)=]

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

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

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

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

Ify = (1 + tan.4) (1-tan B), where AB = (pi) / (4) (y + 1) ^ (y + 1) i sequalt

If tan^(-1)x+tan^(-1)y=(pi)/(4), then write the value of x+y+xy.

If y=tan^(-1)(1)/(2)+tan^(-1)b,(0 =(pi)/(4) then the maximum value of b is (1)/(2)(b)-1 (c) (2)/(3)(d)

If A-B=pi/4quad y=(1+tan A)(1-tan B) then value of (y)^(y+1)=

If "tan"^(-1)x+"tan"^(-1)y=pi/4,xylt1 , then write the value of x+y+xy .
