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?
