1 1/x has oscillation â at x = 0, and oscillation 0 at other finite x and at ââ and 2  +â. sin (1/x) (the topologist's sine curve) has oscillation 2 at x = 0, and 0 elsewhere. 3  sin x has oscillation 0 at every finite x, and 2 at ââ and  +â. The sequence 1, â1, 1, â1, 1, â1, ... has oscillation 2.
An herbicide is a chemical used to kill or inhibit the growth of weeds and other unwanted plant pests. There are two kinds of herbicides. Species-specific herbicides are designed to kill a specific kind of plant only, leaving other desirable plants unharmed.hen should you use an herbicide? An herbicide is appropriate any time that you have pest plants or weeds that are competing with desired plants or crops for space, water, light, and nutrients. They are often used in lawn and garden care to achieve a desired aesthetic effect.
Surfactant for Herbicides is a wetting agent with 80% non-ionic surfactant for increasing the penetration, coverage and overall effectiveness of almost any herbicide. Surfactant for herbicides can be used with almost all herbicide sprays including TrimecÂ®, Atrazine, Brush Killer and 2, 4-D Amine.Please check the herbicide product label first to see if a surfactant is recommended.pplication: HERBICIDES such as 2,4-D Amine, Atrazine, Trimec, Brush Killer, Image, MSMA and others: 1-2 teaspoons per gallon of water, or 1 pint per 100 gallons. GLYPHOSATE HERBICIDES (that do not contain a surfactant): 1 Tablespoon per gallon or 2 quarts per 100 gallons of spray.
