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.
Scoria Scoria is the vesicular ejecta of basaltic and andesitic magmas. Generally a dark brownish black or red, scoria is generally thought of as the mafic version of pumice, forming when magma rich in dissolved gases is vented.Scoria is composed of volcanic glass fragments, and has few mineral crystals.Its specific gravity ranges from 0.8 to 2.1, making it a relatively light form of rock-sometimes light enough to float (at less than 1.0 specific gravity).coria is composed of volcanic glass fragments, and has few mineral crystals.
