Algebraic curves | Roulettes (curve) | Articles containing proofs
In geometry, the cissoid of Diocles (from Ancient Greek κισσοειδής (kissoeidēs) 'ivy-shaped'; named for Diocles) is a cubic plane curve notable for the property that it can be used to construct two mean proportionals to a given ratio. In particular, it can be used to double a cube. It can be defined as the cissoid of a circle and a line tangent to it with respect to the point on the circle opposite to the point of tangency. In fact, the curve family of cissoids is named for this example and some authors refer to it simply as the cissoid. It has a single cusp at the pole, and is symmetric about the diameter of the circle which is the line of tangency of the cusp. The line is an asymptote. It is a member of the conchoid of de Sluze family of curves and in form it resembles a tractrix. (Wikipedia).

A Level Chemistry Revision "Cis-Trans Isomers"
In this video, we look at a special class of isomers called cis-trans isomers. First we explore why we can see cis-trans isomers in alkenes and how this is due to the double bond. We then look at the features that a molecule must show in order to have cis-trans isomers. Finally, we look at

Epoxidation of Alkenes - DMDO, mCPBA, & NaOCl (IOC 26)
In this episode, I discuss the epoxidation of electron-rich and electron-poor olefins, using peracids, DMDO, hydrogen peroxide, and sodium hypochlorite (NaOCl). *Note: for some reason, I didn't manage to pronounce MMPP correctly; it's full name is magnesium monoperoxyphthalate. *WARNING*

A tutorial: some differential geometry problems | Differential Geometry 21 | NJ Wildberger
Here we go over in some detail three problems that were assigned earlier in the course: the rational parametrization of the cissoid, the parametrization of a particular conic x^2-4xy-2y^2=3, and finding the evolute of the curve y=x^n for a general n. Note that in my diagram around 14:00
