Top. A horizontal asymptote is a y-value which a function approaches. The asymptote is parallel to x axis, so is of the form y = a, for all real values of a. Thus if f(x) = y is a function, then y = a, becomes undefined for the function, then the line y = a, is called the asymptote for the function y = f(x).
The African armyworm (Spodoptera exempta) also called okalombo, kommandowurm, or nutgrass armyworm, is an African moth. It is a very deleterious pest, capable of destroying entire crops in a matter of weeks.
1 Life is often stranger than fiction as filmmaker Rick Beyer found out when he learned that an American Ghost Army helped defeat the Germans during World War II. 2  Only nothing the Germans heard or saw was real. Hundreds of inflatable tanks and other military vehicles were props in an elaborate ruse, one of many that a small group of American soldiers staged to distract the enemy. They were known as the Ghost Army. The 1,000 men in this unit were basically pretending to be two divisions of 30,000 men and trying to convince the Germans that they were attacking across the Rhine in one place where the real attack was going to take place 10 miles away, said filmmaker Rick Beyer.
