This online tutorial site shows that the concavity of a function is related to the second derivative of the function by using an online graphing system. Inflection points are also briefly discussed.

Examples are presented to demonstrate the steps for sketching curves that are not polynomials. Using x- and y-intercepts, limits, domain and range, maxima and minima, second derivatives and general behavior the graphs are constructed...

A statue that actually consists of two statues; the first is a kneeling man presenting the second one, which represents Osiris, the god of the dead. The term "naophorous statue" is derived from the word "naos" which means "shrine" in...
