Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a symmetric matrix A, prove that all of its eigenvalues are real.

💡 Hint: Consider applying the spectral theorem.

Challenge 2 Hard

In an engineering application, a stress tensor is symmetric and its eigenvalues represent principal stresses. If the principal stresses are found to be λ1 = 5, λ2 = 3, λ3 = 2, how would you interpret these in terms of material selection?

💡 Hint: Think about the implications of stress distribution in materials.
