When surveying the computer technology available for working out mathematical problems, one fact quickly becomes apparent-most personal and super- computers are not designed for computation. Without the aid of costly and often only partially compatible software programs, most computer operating systems cannot perform mathematical computations. Mathematics textbooks and handbooks provide useful equations, but they do not offer accessible means for evaluation. The HP48SX, an object-oriented computer containing a custom CPU and operating system, is designed specifically for this task. With a low-cost computer chip and an inexpensive calculator, the HP 48SX Engineering Mathematics Library: An Introduction to Symbolic and Complex Computation with Applications package offers users an affordable and versatile alternative for solving simple and complex problems.
Key Features
* Offers single-button plotting of all HP 48, MATHLIB, and all real and complex functions stored in the VAR directory-linear, semi-log and log-log lots with titles and labeled axes
* Creates 36 user-defined programmable command menus, instead of offering users stock, menu-driven commands
* Supports many different fields of study, (including physicists, and electrical, mechanical, and aerospace engineers), where computation ranges from basic to advanced mathematics
* Provides extensive symbolic algebra, calculus, and linear algebra tools
* Features menus and a manual logically built around subject areas
* Allows for over 300 tabulations of complex math functions, most within 10-digit accuracy
* 100 statistical operations and tests plus 50 statistical probability distributions and their inverses
* 100 data and signal processing operations
* 200 vector and matrix commands, plus 50 symbolic array commands
* 200 algebra operations, including 3 powerful complex-coefficient polynomial root-solvers
* 50 data editing, sorting, windowing, clipping, and peak and valley analysis commands
* Can solve a 40 x 40 linear system of equations with iterative refinement in under 4 minutes
