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 what is cot ( A -B) equal to ?

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

(i) If tanA-tan B=x and cot B- cot A=y . Prove that cot(A-B)=1/x + 1/y . (ii) If 2 cos A = x+1/x, 2 cos B = y + 1/y , then show that 2 cos (A-B)= x/y+y/x .

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

tan A-tan B=x and cot A-cot B=y prove that cot(A-B)=(1)/(x)-(1)/(y)

tan A-tan B=x and cot A-cot B=y prove that cot(A-B)=(1)/(x)-(1)/(y)

If tan A+tan B=p and cot A+cot B=q then cot(A+B)=

If tan A+tan B=a and cot A+cot B=b prove that: cot(A+B)=(1)/(a)-(1)/(b)

If tanA-tan B=x , and cot B-cotA=y , then find the value of cot(A-B) .
