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.

So perfectly soft
Size: King, Style: 2 Dark Gray
My husband was complaining about the mattress, and wants to spend a lot of money on a new one like the ones at the Waldorf. I asked him to give me a chance to try to fix it first. Watched youtube videos about hotel style beds, and landed on the need for a mattress topper. This one is so... very... comfortable. I thought the grid pattern would bother me, but nope. You don't realize how much heat you soak up from your mattress until you get a nice airy layer in between. I almost completely stopped sweating at night, and he's stopped complaining about hurting as much. This is another of those items that I'm scared of washing too much, but it's held up with care and caution. If it starts to get a bit too squished, I just fluff it in the dryer and the padding poofs right back up. The sides are deep and my mattress sinks right into the pocket with no pulling. I have bad back pain and I am certain this has been helping support my back a bit better, so I wake up more refreshed. I'm sorta popping out of bed like I used to years ago. He still plans on a new mattress, but this has saved us money, for now, and when we get the new one, this will layer on top like a dream. I'm glad I took the chance on this, it has really improved our rest, and that's so important.

Soft and pretty
Size: Full, Style: 1 Green
Not as thick as I thought it would be. That doesn't matter, though. Being thinner made it easier to handle and I like that. Actually, over all this is a good product. Placing it in the outdoors to sun out a bit took the odor away quickly. I think my company will be impressed with the comfort.

Very comfortable
Size: 36" X 24", Color: Grey, Size: 36" X 24", Color: Grey
Very soft and dries fast. I did the scoot test on them to test the grip and they passed with flying colors. Got them on a limited deal and it was worth every penny. I will be purchasing more in different colors as there are plenty of options. I haven’t washed them yet but if there’s an issue, I will definitely update this review. They are nice and thick and fell good on your feet.

Nice shower mat
Size: 50" X 30", Color: Navy
I have had it for almost a month now and run it through the washer and dryer. Its nice and soft, decent size I did not use a measuring tape to check how precise the sizing is. Absorbs the water when I step out of the shower well and doesn't feel wet or let anything through. Stays in place on the tile floor. Only challenge has been the robot vacuum cleaner gets trapped on it about half the time, but this might just be a testament to its thick nature.

Soft and washes well.
Size: 30" X 20", Color: Grey
These are great rugs and I keep going back and buying more. They are such a good value for money and they wash really easily. They don't slide or shed and they are very durable. They are very soft.So far we have them in both bathrooms and next to our bed.
