use a determinent [sic] to determine whether the given points are coplaner [sic]
\n" ); document.write( "(-4,1,0)(0,1,2)(4,3,-1)(0,0,1)
\n" ); document.write( "----------
\n" ); document.write( "Use the method for determining the volume of a tetrahedron.
\n" ); document.write( "If the volume = 0, they're coplanar.
\n" ); document.write( "==========
\n" ); document.write( "PS it's determinant & coplanar.
\n" ); document.write( "
\n" );
