Find all solutions of the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to two decimal places where appropriate.)
\n" ); document.write( "4 cos θ + 1 = 0
\n" ); document.write( "cos θ=-1/4
\n" ); document.write( "reference angle≈1.32 in quadrants II and III where cos<0
\n" ); document.write( "θ≈1.82+2πk, 4.46+2πk, k=any integer \n" ); document.write( "

\n" );
