Based on a Brown University course in applied mathematics, this rigorous and demanding treatment focuses on specific analytical methods. It emphasizes nonlinear problems, acquainting readers with problems and techniques in ordinary differential equations. The material is presented in a manner that prepares students for informed research of differential equations, teaching them how to be more effective in studies of the current literature. In addressing the applied side of the subject, the text devotes considerable attention to specific analytical methods common to applications.Introductory chapters offer necessary background material by reviewing basic facts of analysis and covering the general properties of differential equations. Topics include two-dimensional systems, linear systems and linearization, perturbations of noncritical linear systems, simple oscillatory phenomena and the method of averaging, and behavior near a periodic orbit. Additional subjects include integral manifolds of equations with a small parameter, periodic systems with a small parameter, alternative problems for the solution of functional equations, and the direct method of Liapunov. Exercises appear at the end of each chapter, and the appendix contains a convenient reference for almost every periodic functions.

Healthy, Compliant, & Convenient — But a Bit Pricey
Flavor Name: Original Beef
I’ve been enjoying Chomps Grass‑Fed Beef Sticks regularly. Made from 100% grass-fed & finished beef, they’re Whole30, keto-, paleo-, and gluten‑friendly with zero added sugar, perfect for those following strict eating plans. Each stick delivers around 10 g of protein and 100 calories, making them a satisfying, portable snack. The flavor is solid, savory, meaty, and not overly salty. The texture is pleasantly chewy. On the flip side, they’re noticeably more expensive than typical meat sticks. If you’re buying regularly, costs can add up unless you shop bulk.

Tasty product
Flavor Name: Original Beef
Chomps it’s probably the most healthy choice you can choose or beef jerky. I really like it, but I think it is on the expensive side.

Great Chomps!

My husband and I loved the taste of the Chomps. He was ok with the Chomps. I was thirsty after eating one. Enjoyed the taste though.

Tasty snack
Flavor Name: Original Beef
I love chomps for the protein, taste, and ease of eating. Comes in many flavors. My only complaint is that it is pricey. I’m willing to pay because it is grass fed beef, zero sugar, and made with real ingredients.
