This page contains an applet to help you explore polynomials of degrees up to 5: f(x) = ax5 + bx4 + cx3 + dx2 + ex + f. by changing the values of the coefficients a, b, c, d, e and f. It is not easy to draw any conclusion when you change all 5 coefficients at the same time. You can always reduce the degree (highest power) by setting some parameters to zero. For example if you set parameter a to zero and b to a non zero value, you obtain a polynomial of degree 4.
What is a nautilus? The nautilus is a mollusk that uses jet propulsion to roam the ocean deep. Writers, artists, and engineers have long marveled at the nautilusâs beauty and swimming abilities. The chambered or pearly nautilus is a cephalopod (a type of mollusk)âa distant cousin to squids, octopi, and cuttlefish. Unlike its color-changing cousins, though, the soft-bodied nautilus lives inside its hard external shell. The shell itself has many closed interior chambers or âcompartments.â.
Naticidae, common name the moon snails or necklace shells, is a family of minute to large-sized predatory sea snails, marine gastropod molluscs in the clade Littorinimorpha.The shells of the species in this family are mostly rather globular in shape.Naticidae is the only family in the superfamily Naticoidea. It has been estimated that worldwide there are about 260â270 Recent species of naticid snails.This group is assumed to have originated in the late Triassic or in the early Jurassic.he shells of the species in this family are mostly rather globular in shape. Naticidae is the only family in the superfamily Naticoidea. It has been estimated that worldwide there are about 260â270 Recent species of naticid snails.
