If ` x= tan A - tan B , y= cot B- cot A " then " (1)/(x)+(1)/(y)=`

If tan A - tan B =x and cot B - cot A=y, then: cot(A-B)=

If tan A - tan B = x and cot B - cot A= y, then cot (A-B) is

If tan A-tan B=x and cot B-cot A=y, then cot (A-B)=

If tan A-tan B=x,cot B-cot A=y prove that cot(A-B)=(1)/(x)+(1)/(y)

If tan A-tan B=xand cot B-cot A=y prove that cot(A-B)=(1)/(x)+(1)/(y)

If tan x - tany = a and cot y - cot x =b , then cot (x-y) is

If tan - A tan B = x, cot B - cot A = y prove that cot (A - B) = (1)/(x) + (1)/(y)

If tan A - tan B = x and cot A - cot B = y, then cot( A- B) =
