Culottes are a form of split skirt. They are usually made full or calf length, and consist of a pair of loose, flowing trousers which strongly resemble a skirt until the wearer engages in vigorous physical activity. The shorter version is a skort, a pair of shorts with a flap of fabric in the front that turns them into a more modest skirt.
In the mathematical theory of singularities a cusp is a type of singular point of a curve. Cusps are local singularities in that they are not formed by self intersection points of the curve.The plane curve cusps are all diffeomorphic to one of the following forms: x 2 â y = 0, where k â¥ 1 is an integer. An ordinary cusp is given by x 2 â y 3 = 0, i.e. the zero-level-set of a type A 2 -singularity. 2  Let f (x, y) be a smooth function of x and y and assume, for simplicity, that f (0,0) = 0. 3  Then a type A 2 -singularity of f at (0,0) can be characterised by:
