Archimedean Spiral top; You can make a spiral by two motions of a point: There is a ... You give a point by a pair (radius OP, angle t) in the (simple) polar equation. The radius is the distance of the point from the origin (0|0). The angle lies between the radius and the positive x-axis, its vertex in the origin.

2) It can be proven that the desired curve is the logarithmic spiral: the curve can be found as the solution of the differential equation, which results out of the relation y' = tan(b + F): Substituting y = x z and rewriting in polar coordinates gives the spiral's equation.

The Archimedes' spiral (or spiral of Archimedes) is a kind of Archimedean spiral. Some authors define this spiral as the combination of the curves r = F and r = - F. Because there is a linear relation between radius and the angle, the distance between the windings is constant.

The parametric equation of the spiral is a little more difficult and having to use a different form of the equation, given; ... Abstract: The equiangular spiral, a mathmatical curve with polar equation r = r*k^theta, was examined from the definition and the polar equation, parametric equations were derived and shown.
