Conchoid (mathematics)
In geometry, a conchoid is a curve derived from a fixed point O, another curve, and a length d. It was invented by the ancient Greek mathematician Nicomedes. (Wikipedia).

Macroscopic Characteristics of Minerals Part 2: Cleavage and Hardness
After examining color and luster, let's look at two more characteristics of minerals, cleavage and hardness. How do minerals break apart? How well do they scratch certain surfaces? Let's get a closer look! Script by Jared Matteucci Watch the whole Geology playlist: http://bit.ly/ProfDave

Curves from Antiquity | Algebraic Calculus One | Wild Egg
We begin a discussion of curves, which are central objects in calculus. There are different kinds of curves, coming from geometric constructions as well as physical or mechanical motions. In this video we look at classical curves that go back to antiquity, such as prominently the conic sec

11_6_1 Contours and Tangents to Contours Part 1
A contour is simply the intersection of the curve of a function and a plane or hyperplane at a specific level. The gradient of the original function is a vector perpendicular to the tangent of the contour at a point on the contour.

What is the difference between convex and concave
๐ Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1
