Trigonometry has always been an underappreciated branch of mathematics. It has a reputation as a dry and difficult subject, a glorified form of geometry complicated by tedious computation. In this book, Eli Maor draws on his remarkable talents as a guide to the world of numbers to dispel that view. Rejecting the usual arid descriptions of sine, cosine, and their trigonometric relatives, he brings the subject to life in a compelling blend of history, biography, and mathematics. He presents both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social development. Woven together in a tapestry of entertaining stories, scientific curiosities, and educational insights, the book more than lives up to the title Trigonometric Delights.
?


Maor, whose previous books have demystified the concept of infinity and the unusual number e, begins by examining the proto-trigonometry of the Egyptian pyramid builders. He shows how Greek astronomers developed the first true trigonometry. He traces the slow emergence of modern, analytical trigonometry, recounting its colorful origins in Renaissance Europe's quest for more accurate artillery, more precise clocks, and more pleasing musical instruments. Along the way, we see trigonometry at work in, for example, the struggle of the famous mapmaker Gerardus Mercator to represent the curved earth on a flat sheet of paper; we see how M. C. Escher used geometric progressions in his art; and we learn how the toy Spirograph uses epicycles and hypocycles.


Maor also sketches the lives of some of the intriguing figures who have shaped four thousand years of trigonometric history. We meet, for instance, the Renaissance scholar Regiomontanus, who is rumored to have been poisoned for insulting a colleague, and Maria Agnesi, an eighteenth-century Italian genius who gave up mathematics to work with the poor--but not before she investigated a special curve that, due to mistranslation, bears the unfortunate name the witch of Agnesi. The book is richly illustrated, including rare prints from the author's own collection. Trigonometric Delights will change forever our view of a once dreaded subject.

The cold side really works. It's nice ;)
Size: King (2 Pack)
The soft side aspect of it is really awesome. We like the whole cold pillow thing but personally I feel like it keeps my head too high up so I wake up with a neck pain. But for someone who likes support, this would be a perfect option.

Perfect pillow
Size: Queen (2 pack)
Very comfortable! A light firmness yet you sink into the pillow perfectly. Keeps shape. Fluff right back up instantly when you leave it. Supports and the quality is great for the price.

Love these pillows!
Size: Queen (2 pack)
I’m a side and stomach sleeper. I’ve bought so many pillows recently trying to find one that doesn’t kill my neck or shoulder. I felt like I was looking for a unicorn. For some reason this pillow just works. It has a higher loft, which I prefer, but it’s also super squishy, which I also prefer. It somehow has the best of both worlds. They feel high quality, are adjustable in terms of density since you can remove as much filling as you want, they actually fill my pillowcases so they’re not flopping around the pillow, and they maintain their shape after a full night of sleeping on them, the price point for two pillows is just right, and best of all, they actually stay cool. I am a hot sleeper so that last point is worth the cost of entry all by itself. I have no neck or shoulder pain after getting a full night’s sleep on these pillows. The only negative is the initial smell of the pillows. It’s pretty strong, but I’m sure this will lessen over time.
