Find the exact value of each expression
\n" ); document.write( "a) sin 8π/3=-1 (reference angle=2π/3)
\n" ); document.write( "b) cos 8π/3=0 (reference angle=2π/3)
\n" ); document.write( "c) sin 11π/4=√2/2 (reference angle=3π/4) in quadrant II
\n" ); document.write( "d) cos 11π/4=-√2/2 (reference angle=3π/4) in quadrant II
\n" ); document.write( "
\n" );
