In this age of omnipresent digital computers and their capacity for implementing numerical methods, no applied mathematician, physical scientist, or engineer can be considered properly trained without some understanding of those methods. This text, suitable for advanced undergraduate and graduate-level courses, supplies the required knowledge -- not just by listing and describing methods, but by analyzing them carefully and stressing techniques for developing new methods.Based on each author's more than 40 years of experience in teaching university courses, this book offers lucid, carefully presented coverage of norms, numerical solution of linear systems and matrix factoring, iterative solutions of nonlinear equations, eigenvalues and eigenvectors, polynomial approximation, numerical solution of differential equations, and more. No mathematical preparation beyond advanced calculus and elementary linear algebra (or matrix theory) is assumed. Examples and problems are given that extend or amplify the analysis in many cases.

Happy pup. Worth it.
My dog loves this thing. It takes hardly any effort to launch the ball. Flick of the wrist kinda thing. The squeaky ball is her favorite but unfortunately you can't buy this brand of ball separately. It says compatible with any 2.5 inch ball but that's not true. We have a ton of Penn tennis balls and they are just slightly too big for this launcher. You can do it but it's a huge pain and hard to throw. Another issue is that when we first got it the handle didn't want to stay screwed together. After the first day of use and having to rescrew it together multiple times, the issue seems to have corrected itself? Either way, for the price with the comfy handle, very low effort throwing for big pay off, two balls included and the crazy excitement from my dog anytime we get near the thing. It's definitely worth it. I like it much better than the chuck it and stone random cheap brand we used to have. I'm going to try one of the balls recommended in the product pictures. I'll update if they work out.

Ergonomic and well made.
I have at least a half dozen ball launchers and this is the nicest one. As efficient as any of them and it feels the nicest in my hand. As long as you tighten the handle when you put it together, it will serve your puppy well.

Ball Launcher Poorly Made and Hard To Use, Save Your Money
This launcher was too long and thin to pick up the ball from the ground, I had to use my other hand to press down on it. The screw on handle was heavy and kept coming loose no matter how tight I made it, strain on the wrist to use. The ball holder end would often not let go of the ball when trying to launch it. I ended up putting it in the trash. I had two shorter Chuckit launchers that are much better made, will stick with them. I don't recommend this to anyone, save your money.

Go Get It!
GoSports does it again.
Our family has a lot of GoSports products. It brings us comfort knowing when we order a product from them the quality is going to be great.
The Ball Launcher is excellent. Our lab loves the soft tennis balls that come with it, preferring them over the harder rubber ones from other brands.
The launcher itself is thoughtfully designed, well-made, and comfortable to hold.
Our new go-to for daily fetch sessions.
