WebJun 24, 2005 · Any 2 by 2 symmetric matrix must be of the form for some numbers a, b, c. Taking a= 1, b= c= 0 gives . Taking a= 0, b= 1, c= 0 gives . Taking a= b= 0, c= 1 gives . Those matrices form a basis for the 3 dimensional space. In other words, write the general matrix with constants a, b, etc. and take each succesively equal to 1, the others 0.
