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

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

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

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

If A + B = 45^@ , then (cot A-1) (cot B-1) is equal to......... A) 0 B) 2 C) 1 D) 4

If A+B=45^(@), then (cot A-1)(cot B-1) is equal to

If A + B = (pi)/(4) , show that (cot A - 1) (cot B - 1) = 2 and hence deduce that cot 22^((1^(0))/(2))=sqrt(2)+1.

If A+B=(3 pi)/(4) and n=(1+cot A)(1+cot B) then the value of sin((n pi)/(n+1)) is equal to

IF A +B = 45 ^@ , then ( cot A -1) ( cot B-1) is equal to

If A+B=45^@ then then (cot A- 1) (cot B- 1) is equal to :
