\n" );
document.write( "Hi
\n" );
document.write( "4 cos 210 degrees + 3 tan 330 degrees 
\n" );
document.write( " 4(-sqrt(3)/2) + 3((-1/2)/(sqrt(3)/2)
\n" );
document.write( "  -2sqrt(3) - 3/sqrt(3)= -2sqrt(3) - 3sqrt(3)/3 = -3sqrt(3)
\n" );
document.write( "Thought this (cosx, sinx) summary may be helpful to You.
\n" );
document.write( " \n" );
