A simple modification of the Euler method which eliminates the stability problems noted in the previous section is the backward Euler method: + = + (+, +). This differs from the (standard, or forward) Euler method in that the function is evaluated at the end point of the step, instead of the starting point.
*Artemis*. Artemis is the Goddess of the Hunt. She had 50 hounds and 50 Draiads (wood nymphs) and a quiver full of painless silver arrows. Along with her twin brother Apollo, she was the daughter of Zeus and Leto as well as being youngest of the three maiden goddesses (in addition to Hestia and Athena).
The Mistress of the Hearth. Hestia is the ancient greek goddess of hearth and home. She dwells in the flames of every altar and fireplace. In Rome she was known as Vesta and an important state goddess. Although an important deity in Greek religion, she is rarely shown in art, and has virtually no mythology and iconography.
