`cotB-cotA=b ,tanA-tanB=a`,find`cot(A-B)`.

If tanA-tanB=x a n dcotB-cotA=y , prove that cot(A-B)=1/x+1/y

If tanA-tanB=x and cotB-cotA=y , then cot(A-B) . is equal to (i) 1/y-1/x (ii) 1/x-1/y (iii)1/y+1/x (iv) 1/(x+y)

If (tanA-tanB)=x and (cotB-cotA)=y ,then cot(A-B)

If tanA-tanB=x and cotB-cotA=y , then cot(A-B)=?
