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( "15 cot^2(x) = 5
\n" ); document.write( "cot^2(x)=5/15=1/3
\n" ); document.write( "cot(x)=1/√3
\n" ); document.write( "x=π/3, 4π/3 (in quadrants I and III where cot>0) \n" ); document.write( "

\n" );
