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).
Many of the goddess symbols come from the myths featuring a specific goddess and were characters in her story. Other goddess symbols were derived from the rituals used in the ancient rites of worship of these pagan goddesses. Hestia (also known as the Roman goddess Vesta) is often represented by goddess symbols associated with her personality traits, the sacred flame, and her contribution to civilization, personal households, and to architecture.
