Find all values of x in the interval [0, 2π] that satisfy the equation. (Enter your answers as a comma-separated list.)
\n" ); document.write( "9 cot2(x) = 3
\n" ); document.write( "cot^2(x)=3/9=1/3
\n" ); document.write( "cot(x)=1/√3
\n" ); document.write( "tan(x)=1/cot(x)=√3
\n" ); document.write( "x=π/3, 4π/3 (reference angles in quadrants I and III where cot and tan>0) \n" ); document.write( "
\n" );
