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).
She is also frequently depicted holding a kettle (a symbol of the hearth) and also cut flowers (symbolizing domesticity). Like the goddess Bastet in Egyptian belief, Vesta was of special service to women but was popular with both sexes. She was the proctectress of Rome in that she cared for and maintained the homes of each of its citizens.
