TangentsTangents of both affine and projective algebraic curves. These are related to multiplicity of intersection of lines with curves, and the notion of singular points, and the order (multiplicity) of a point on a curve.

Bézout’s TheoremDefining intersection multiplicity of two curves at a point. Two definitions are given: one is used to show geometric invariance of intersection multiplicity, the other is conceptually simpler. A “categoricity” property of intersection multiplicity is then used for quick computations.
