EE 231_B1 Numerical Analysis for Electrical and Computer Engineers Course Instructor: Dr. Sergiy Vorobyov - 1 - Solutions to Assignment 6 9.5 (a) The equations can be expressed in a format that is compatible with graphing x 2 versus x 1 : The resulting plot indicates that the intersection of the lines is difficult to detect: Only when the plot is zoomed is it at all possible to discern that solution seems to lie at about x 1 = 14.5 and x 2 = 10.

EE 231_B1 Numerical Analysis for Electrical and Computer Engineers Course Instructor: Dr. Sergiy Vorobyov - 2 - (b) The determinant can be computed as which is close to zero. (c) Because the lines have very similar slopes and the determinant is so small, you would expect that the system would be ill-conditioned (d) Multiply the first equation by 1.02/0.5 and subtract the result from the second equation to eliminate the x 1 term from the second equation, The second equation can be solved for This result can be substituted into the first equation which can be solved for (e) Multiply the first equation by 1.02/0.52 and subtract the result from the second equation to
