Description

Shadows of the CircleThe aim of this book is to throw light on various facets of geometry through development of four geometrical themes. The first theme is about the ellipse, the shape of the shadow cast by a circle. The next, a natural continuation of the first, is a study of all three types of conic sections, the ellipse, the parabola and the hyperbola. The third theme is about certain properties of geometrical figures related to the problem of finding the largest area

The aim of this book is to throw light on various facets of geometry through development of four geometrical themes.

The first theme is about the ellipse, the shape of the shadow cast by a circle. The next, a natural continuation of the first, is a study of all three types of conic sections, the ellipse, the parabola and the hyperbola.

The third theme is about certain properties of geometrical figures related to the problem of finding the largest area that can be enclosed by a curve of given length. This problem is called the isoperimetric problem. In itself, this topic contains motivation for major parts of the curriculum in mathematics at college level and sets the stage for more advanced mathematical subjects such as functions of several variables and the calculus of variations.

Good quality
Color: Crisp White, Size: Medium
Fit is great, feels like a durable material. Generally a very nice shirt! Bought this for a 5’ 10” male who is 150lbs. Medium was just right, with a little bit of breathing room.

Good for an emergency only
Color: Crisp White, Size: X-Large
Shirts are good overall, but the material is too light ... if you are hairy or have dark skin, you need an undershirt; otherwise, it looks like the shirt is dirty.

love the shirt and they fit well for an overweight man. All the ones I got are consistent in size and you don't see that often.

Excellent style and quality for price
Color: Grey Blue, Size: Medium
Very nice quality and affordable price. Fabric is soft and smooth, very few wrinkles after washing and drying and easy to iron. Seems durable for machine washing and drying. Fits true to size.
