Three exercises from Chapters 2–3 worked end-to-end: dual cones, KL divergence, second-order convexity. What a clean study deck looks like for a hard textbook.
Solve exercise 2.31: Properties of dual cones.
Solve exercise 3.13: Kullback-Leibler divergence and the information inequality.
Solve exercise 3.8: Second-order condition for convexity.
