7. Summary

The following table shows the mean square error (represented by the norm ||err||, the square-root of the sum of the squares of the errors) and the maximum absolute error for each of the approximations discussed above:

	RP1	TA1	TA2	LLSQ	MinMax
||err||	0.1301	0.1516	0.0586	0.0138	0.0147
max|err|	0.0469	0.0858	0.0392	0.0075	0.0049
