Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.I think I did this question once here.
cotAcotB can be written in terms of cot(A±B) and cotB±cotA
Do it in terms of cot(A+B) for the first two terms (you get 60° and 120°) and cot (A-B) for the last one, as you get 60°
And the rest cancel out uirc
*iirc
-3 should be the answer.
