Question 746087
 Solve the equations for solutions over the interval [0,360 degree) Question: 
18 tan x -6 cot x=0
6(3tan(x)-cot(x))=0
{{{3tan(x)-cot(x)=0}}}
{{{3tan(x)-1/tan(x)=0}}}
{{{3tan^2(x)-1=0}}}
{{{tan^2(x)=1/3}}}
take sqrt of both sides
{{{tan(x)=1/sqrt(3)}}}
x=30º or 210º (in Q1 and Q3 where tan>0)
