Description
Mathematical Methods in Physics and EngineeringIntended for college level physics, engineering, or mathematics students, this volume offers an algebraically based approach to various topics in applied math. It is accessible to undergraduates with a good course in calculus which includes infinite series and uniform convergence.

Intended for college-level physics, engineering, or mathematics students, this volume offers an algebraically based approach to various topics in applied math. It is accessible to undergraduates with a good course in calculus which includes infinite series and uniform convergence. Exercises follow each chapter to test the student's grasp of the material; however, the author has also included exercises that extend the results to new situations and lay the groundwork for new concepts to be introduced later. A list of references for further reading will be found at the end of each chapter.For this second revised edition, Professor Dettman included a new section on generalized functions to help explain the use of the Dirac delta function in connection with Green's functions. In addition, a new approach to series solutions of ordinary differential equations has made the treatment independent of complex variable theory. This means that the first six chapters can be grasped without prior knowledge of complex variables. However, since Chapter 8 depends heavily on analytic functions of a complex variable, a new Chapter 7 on analytic function theory has been written.

Have bought a few of these over the last handful of years
Color: Red
Best toy outside of Ghonuts for heavy chewers. Even outlasts the most durable Kongs. I'd say we get about four months before our dog starts really making a dent in it and the size of the pieces he pulls off start to become larger and I should probably replace it after about six months. It's cheap enough that replacing it that often is fine.
*Important note* using squishy toys for heavy chewers is really important. They can break their teeth on hard toys like Nyla bones and things like antlers can break and cut them and damage their digestive system if they swallow the shards. It sucks because my dog loved Nyla bones and would chew off an inch a day, but I couldn't risk his teeth like that.

Finally - a tug toy my dog hasn’t destroyed!
Color: Red
This completely exceeded my expectations! My dog is roughly a year old, about 110-115lbs and a TOUGH chewer. He loved tugs toys but none of them last more than 10 minutes with him. I decided to try this because of the other reviews and price but wasn’t expecting it to last long. He’s had it almost a week and it’s still completely intact. It’s definitely heavy so it might not be best for smaller dogs but if you have a big dog/heavy chewer definitely give this a shot!

Indestructible so far
Color: Red, Color: Red
My toy destroyer has had this for almost two months now and it hasn’t taken any damage. It is big and heavy and solid. It became one of his favorites immediately and goes in and out of the house and even to bed with him.
Now if only we could find a stuffy that he can’t destroy.

MY DOG'S AREN'T INTERESTED ...
Color: Red
This is a large, heavy, hard rubber toy, so is of high quality. However, it is SO heavy that neither my 60-lb. female Boxer nor my 80-lb. male Bully will 'play' with it at all. They don't even chew on it. So, although it would probably be pretty indestructible, I have no way to verify that, since neither of my dogs show any interest at all. I've tried encouraging them, by holding on one end of it and encouraging them to grab the other end, but even that didn't work. Perhaps a much larger 'giant' breed dog would enjoy it.

Tough chewer for sure
My dog destroys toys. These are amazing, she chewys on them tell she's a slobbery mess. And they are holding strong. Glad a found these!
