Hi, could someone show me how this one's done? Find all solutions for X, satisfying 0 < X < (two pi): 2cotX = tanX Thanks, your help would be much appreciated!

Supposing that You can devide both terms by and after some steps You arrive at the equation which has four solutions, one for each quadrant... Kind regards
Thanks very much!

Thanks very much, that's very helpful.
