Mathematics · Ordinary Differential Equations
For a continuous function q defined on ℝ, consider the ordinary differential equation (ODE): d2ydx2 + q(x)y = 0, x ∈ ℝ. Which of the following statements is FALSE?
- 1There exists a continuous function q such that xex and x(x - 1)ex are solutions of the ODE.
- 2There exists a continuous function q such that ex sin(x) and ex cos(2x) are solutions of the ODE.
- 3There exists a continuous function q such that sin(x) and cos(x) are solutions of the ODE.
- 4There exists a continuous function q such that cos(x) and ex cos(x) are solutions of the ODE.✓
Correct answer
There exists a continuous function q such that cos(x) and ex cos(x) are solutions of the ODE.
