Question

Problem 1: Direct vs. indirect methods 
 Which of the following statements are  true  about direct vs. indirect numerical methods?

Answer

Indirect methods approximate the derivatives in ODE/PDEs and then solve those.

Answer

Direct methods aim to approximate and solve the ODE/PDE directly.

Answer

The Rayleigh-Ritz method is an indirect numerical method.

Answer

Finite differences are an example of indirect methods.

Answer

All direct methods have stability conditions, which limits their applicability.
