"Conic sections" are the four kinds of curves that result when a plane slices through a cone. But if you forgot that bit of high school algebra,... Cooks use math to make beautiful food all the time: ...

Sketch the graph of the ellipse \(\ds \frac{x^2}{9}+\frac{y^2}{16}=1\) and determine its foci. Let \(C\) be the conic which consists of all points \(P=(x,y)\) such ...

MR. TAYLOR's present work is by no means a second edition of his “Geometrical Conies”(1863). His object in this volume is a highly laudable one; from more than one quarter has recently come the ...

The circular shape of constant-energy contours (mapped in reciprocal space) correspond to conic sections of a Dirac-cone. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This solid wooden model is stained ...

Cooks use math to make beautiful food all the time: Slicing eight perfect pieces of pie or doubling a recipe requires basic knowledge of fractions, for example. But how many cooks think about using ...
