(1) For each of the following false statements give a counter-example (i.e. an example set of vectors which demonstrate that the statement is false). You may, but do not have to, reuse your example vectors. (a) If 7 and w are any two vectors then || 7 – w|| = || 7|| – || 1||- %3D (b) If 7 and w are any two non-parallel three dimensional vectors then there is only one unit vector perpendicular to both 7 and w. (c) If 7 and w are any two three dimensional vectors then 7 x w + w × d.
