Another way to define an oblique asymptote for a rational function R(x) is, Since the perpendicular distance between R(x) and the line y = mx+b approaches zero as x becomes unbound. The function R(x) = `(x^2+1)/x`. The degree of the numerator is exactly one more than the degree of the denominator.
An archegonium (pl: archegonia), from the ancient Greek á¼ÏÏÎ® (beginning) and Î³ÏÎ½Î¿Ï (offspring), is a multicellular structure or organ of the gametophyte phase of certain plants producing and containing the ovum or female gamete.
Female gametangia are called archegonia; male gametangia, antheridia. At maturity, archegonia each contain one egg, and antheridia produce many sperm cells. Because the egg is retained and fertilized within the archegonium, the early stages of the developing sporophyte are protected and nourished by the gametophytic tissue.
