Homework Statement


solve, finding all solutions between [0,2pi]
tanx=3cotx

The Attempt at a Solution



It looks like a relatively simple problem if one knew what they were doing unfortunately I do not. I am trying to think of this graphically and I figure that the places were tanx=3cotx are where the functions intersect. but how do i figure out the values?
 
Physics news on Phys.org
I would think about decomposing tan and cot in their sin & cos components and then work from there. Maybe sin^2(x)+cos^2(x)=1 might be helpful, who knows ;)
 
cotx = 1 / tanx
 
got it thx
