document.write( "The component form of the vector V is  V = (3*cos(160°),3*sin(160°)).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, vector V has 2 (two) components   = 3*cos(160°)  and   = 3*sin(160°).\r\n" );

\n" ); document.write( "\n" ); document.write( "It is measured in \"units\".\r

\n" ); document.write( "\n" ); document.write( "Therefore, it is not correct to say \"the magnitude of vector V is 3 points\".\r
