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.
The larvae settle to the sea floor and adopt their distinctive adult radial symmetry. Sea Stars. Sea stars, also known as âstarfishâ, are probably the most well known echinoderm of the sea. The common name âstarfishâ is quickly being replaced by the more accurate term âsea starâ.Since starfish have no relation to fish, the term âsea starâ is preferable.he most striking feature of all echinoderms is their pentamerous radial symmetry. That is, the body can be divided into five parts (or appendages) which point outward from the center of the body. Interestingly, although most mature echinoderms are radially symmetrical, the larvae usually have bilateral symmetry.
