Problem # 1 Determine those values λ for which the following set of equations may possess a nontrivial solution: 3 x 1 + x 2 - λx 3 = 0 4 x 1 - 2 x 2 - 3 x 3 = 0 2 λx 1 + 4 x 2 + λx 3 = 0 . For each permissible value of λ , determine the most general solution. Problem # 2 a) By investigating ranks of relevant matrices, show that the following set of equations possesses a one-parameter family of solutions: 2 x 1 - x 2 - x 3 = 2 x 1 + 2 x 2 + x 3 = 2 4 x 1 - 7 x 2 - 5 x 3 = 2 . b) Determine the general solution. Problem # 3 Determine whether the vector { 6 , 1 , - 6 , 2 } is in the vector space generated by the vectors

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
