यदि `A+B =45^(@) ` तो सिध्द कीजिए कि:
`(cot A-1) (cot B-1) =2`

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

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

If A+B=45^(circ) , prove that (cot A-1)(cot B-1) = 2

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 :

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

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

If, in a Delta ABC , angle C is 45^(@) then : (1 + cot A) (1 + cot B) =
