  1. Set #4, Question 1: When we have y =7y+2x we should conjecture y=C0e7x+C1x+C2.Why include theC2?

  2. Set #4, Question 2: We are testing the function f(x)=C0e2x+C1e-2x as a possible solution to a DE. After we substitute the function and its derivative into the DE we get 2C0e2x -2C1e-2x = -2(C0e2x+C1e- 2x)+3e2x. What value of C0 will allow this function to work as a solution?

  3. Set #4, Question3: We are testing the function f(x)=C0e2x+C1e-2x as a possible solution to a DE. After we substitute the function and its derivative into the DE we get 2C0e2x -2C1e-2x = -2(C0e2x+C1e- 2x)+3e2x. What value of C1 will allow this function to work?

  4. Set #4, Question 4: Which of the following is NOT a solution to y (t)=5y+3t?

  5. Set #4, Question 5: Consider g (z)=ag+bcos(cz) where a, b and c are positive parameters. What will the long-term behavior of the system be?

  6. Set #4, Question 6: We have the equation y =2y+sin(3t). What should our conjecture for y(t) be?
