Homework 7 427K-H due Thursday March 27 Remember there is an exam on March 28 in the lecture room. 1. Find the general solution to the equation Y' = AY where A is the 3x3 matrix [ 1 0 5 ; 1 1 3 ; 0 2 1 ]. 2. If X' = AX give the eigenvalues of A and determine the stability of the fixed or equilibrium point 0 when: a) A= [ 1 , 0 , 2 ; 2 , 2 , 0 ; 5 , -2 , 3 ]. b) A = [ 1 , 0 , 1 , 4 ; 4 , -1 , 0 , 3 ; 3 , - 4 , 0 , 6 ; 1 , 0 , 0 , 10 ]. c) A = [ 1 , -3 ; -2 , 10 ] d) A = [ -2 , 1 , 0 ; -5 , -1 , 0 ; 1 , 0 , 3 ]. 3. Find the general solution of the equation y' = Ay

Consider the 2x2 system of equations y' = Ay where the matrix A depends on an unknown parameter b. A = [ -1 , b ; -1 , 1 ]. Classify the solution [ 0 ; 0 ] as a fixed point for the various values of b. Make specific note of the value of b which is the transition point between the different behaviors of solutions to y' = Ay....

### 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.
