Vanish (brand)

Vanish is a brand of toilet bowl cleaner produced by S. C. Johnson in North America. They obtained the brand through the purchase of The Drackett Company in 1992.

The Vanish name has since accompanied S. C. Johnson's Scrubbing Bubbles brand as a sub-brand.

History

Drackett purchased the product from inventor Judson Dunaway of Dover, New Hampshire, who introduced Vanish in 1937 as a competitor to Sani-Flush, a toilet bowl cleaner made since 1911. The products were substantially the same. The active ingredient in crystal bowl cleaners is sodium bisulfate (also known as sodium hydrogen sulfate). Surfactants are added. This forms sulphuric acid when mixed with water. The last Sani-Flush patent had expired in 1932.

Most other household cleaners are basic (alkaline) in nature.

In 1947, Hygienic Products sued Judson Dunaway on grounds of trademark infringement and unfair competition. Sani-Flush used a yellow 22-ounce can showing a woman pouring bowl cleaner into a toilet. Initially, Vanish sold their product in a white 22-ounce showing the bowl cleaner coming from the bottom of the "I". After WWII, Vanish advertising started to show a woman pouring the product into a toilet bowl, and then a hand, obviously female, pouring powder into a toilet bowl. Dunaway won on appeal.

Zero of a function

A graph of the function cos(x) on the domain , with x-intercepts indicated in red. The function has zeroes where x is , , and .

In mathematics, a zero, also sometimes called a root, of a real-, complex- or generally vector-valued function f is a member x of the domain of f such that f(x) vanishes at x; that is, x is a solution of the equation

In other words, a "zero" of a function is an input value that produces an output of zero (0).

A root of a polynomial is a zero of the associated polynomial function. The fundamental theorem of algebra shows that any non-zero polynomial has a number of roots at most equal to its degree and that the number of roots and the degree are equal when one considers the complex roots (or more generally the roots in an algebraically closed extension) counted with their multiplicities. For example, the polynomial f of degree two, defined by

has the two roots 2 and 3, since

If the function maps real numbers to real numbers, its zeroes are the x-coordinates of the points where its graph meets the x-axis. An alternative name for such a point (x,0) in this context is an x-intercept.
