centred at (0, 0) have eight-way symmetry Similarly to the case with lines, there is an incremental algorithm for drawing circles – the mid-point circle algorithm In the mid-point circle algorithm we use eight-way symmetry so only ever calculate the points for the top right eighth of a circle, and then use symmetry to get the rest of the points

is the anti-symmetric part of A. Notice that xTCx= 0 for any x2Rn. Example: The matrix M= 5 1 1 2! is inde nite. To see this, consider x= (1;0)T and x= (0;1)T: 2.2 Eigenvalues of positive semide nite matrices Theorem 2. The eigenvalues of a symmetric real-valued matrix Aare real. Proof: Let x 2Cn be a nonzero eigenvector of Aand let 2Cbe the ...
