I have a couple of questions on some problems I'm having trouble with
and if anyone could help, it would be much appreciated.

Here they are:

1.Given 4 points on a plane, (3,0,0), (0,0,0), (3,0,5) and (0,0,5),
  (i.e. a plane on the xz plane), how do you determine the equation
  of that plane???

2. Given a matrix A where


		.68	-.6928	.24	0
		.6928	 .5	-.52	0
	A = 	.24	 .52	 .82	0
		 0	  0	  0	1

find a transformation B such that BB=A.

If anyone has any ideas, send mail to ihuxt!barry

Thanks in advance,
ihuxt!barry
