- Iterations.............I believe not? I believe you are correct in
- asserting that the hp48 series uses Newton's method of approximation to
- solve equations. HOWEVER, this is, at best, a singular type of iterative
- process. Say I am analyzing pipe flow. The pipe is made of commercially
- available steel. The limiting conditions on flow within the pipe are that
- it must not exceed 0.5 psi per 200 ft for flow rates up to about 750
- gal/min........a basic fluid mechanics problem. However, the solution is
- necessarily an iterative, that is TRIAL & ERROR, procedure. It may be
- argued that the basis for the procedure may stem from Newton's method of
- approximation but that is only a basis for the procedure. An iterative
- process must be followed outside of such a specific view to obtain the
- result. Therefore, when I say that the hp48 series does not do iterations
- I am refering to a procedural type of multiple equation dependent problem
- and corresponding solution method, that being the most common type.
