# algebraic curve

An algebraic curve is a curve the equation of which involves
only algebraic functions. These
are functions that, in their most general form, can be written as a sum
of polynomials in *x* multiplied
by powers of *y*, equal to zero. Among the most familiar examples are straight
lines and conic sections. Other examples include Neile's parabola, the lemniscate. conchoids, and cissoids.
