HW 2 solutions: questions and re-grade requests to be made to Manu Review: (24 points) 2.1 false 2.2 false 2.3 True 2.4 True 2.5 False 2.6 True 2.7 True 2.8False 2.9True 2.10True 2.22False 2.23True 2.24True 2.25True 2.28No 2.29Yes (all these 1 point each) 2.31 (a) (1 point)State any one out of the four properties from sec 2.2 on page 51 (b)(2 points) Show that having two distinct solutions will lead to the property yuou mentioned in part(a). Anything else will be worth zero points . 2.62 (d) (1 point) 2.63(3 points) 2.65 condition no. > 10^12 (1 point) Note: Most of you in R 2.31 (a) said that the defining property of the matrix to be singular is: “That the "matrix" has more than one solution” which didn't make any sense. A matrix never has solutions. It’s the system of equations that have solutions. Important Note: I made a mistake in grading question2.23. Please all those who lost their points bring their hws to me(Manu) so that I can give you back the 1 point I took off.
