Determine all values of x in the interval [0, 2pi] such that csc=4
\n" ); document.write( "***
\n" ); document.write( "csc=4
\n" ); document.write( "csc=1/sin
\n" ); document.write( "sin=1/4=0.25
\n" ); document.write( "using calculator:
\n" ); document.write( "inverse sin(0.25)≈0.2526,2.8889 radians
\n" ); document.write( "x≈0.2526,2.8889 radians(in quadrants I and II where sin>0)
\n" ); document.write( "
\n" );
