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.

I love this mixer
Size: Basic Frother, Color: Black
I love this mixer. I don't know how we got along before we had this. We have had this small hand mixer for 2 years, using it several times every day, day after day and it finally stopped working and I am ordering another one right now. I can't live without it. I make our bullet coffee with it. My wife makes her morning shake with it. I could go on and on but I need to get another one ordered right now.

Works perfectly!
Size: Basic Frother, Color: Silver
The first unit I got, the charging LED was not working so I don't know if the unit is charged. I returned the unit back to Amazon and got a brand new unit the next day. Great job, Amazon! The 2nd unit has been perform perfectly. I use it to whisk eggs in the morning to make French toasts, waffles, pancakes. All comes out perfect! Also, the mike froth for my morning latte and cappuccino. Don't under estimate this small unit, the spin is fast for high!!! I saw some negative review on the durability of the unit. I hope this is not the case. I'll update if anything changes. As for now, highly recommended!!!

Epic. Works great.
Color: Black
Works great every day. Super powerful and smooth compared to my old battery powered one. The shaft is much thicker and is more securely positioned so I can't imagine it becoming tweaked off balance like my old one. And it comes with an extra mixer attachment! I imagine I've put that away for a long time, but we'll see. Easy to turn on and off with one hand, but I can imagine it being less easy than a simple push button for someone with decreased thumb dexterity or mobility. I do wish the lowest speed was slightly lower, but it hasn't caused any splashing or other detriment. The speed adjustment is very smooth and power is abundant. Love the stand, Usb c charge port is solid, battery life is excellent.
