- This is for those asking about DE's in a recent thread...
-
- After receiving an Educalc catalog, I noticed 2 application cards that
- solve DE's. Here's the info:
-
- "Bringslid - HS/College Math Pac: Algebra, including functions of 1 or
- several variables and graphs, complex numbers and linear equations with
- parameters. Definite integrals. Symbolic integration by partial
- fractions, by parts, by substitution. Improper integrals.
- Differential equations and initial-value problems and separable
- equations. First-order DEs; second-order DEs by undetermined
- coefficients and Lagrange method. Binomial, power and geometric
- series. Convergence by ratio, Leibnitz and integral tests. - $93.95"
-
- "John Holland's - HP48SX Engineering Mathematics Library: Complete,
- with statistics, linear algebra and digital signal and data processing.
- Over 300 tabulations of complex math functions, most to 10-digit
- accuracy. Single-button plotting of all HP48, MATHLIB, and all real
- and complex user-defined functions stored in the VAR directory -
- linear, semi-log and log-log plots with titles and labeled axes. 36
- user-friendly menus. Vector and matrix language, so you can manipulate
- arrays without dealing with the elements. Over 100 statistical
- operations and tests. Over 50 statistical probability distributions
- and their inverses. Over 100 data and signal processing operations.
- Series, rational, and polynomial and least-squares approximations.
- Over 200 vector and matrix commands plus 50 symbolic commands.
- Evaluation of complex contour integrals, residues, symbolic inverse
- Laplace and Z transforms. Runge-Kutta numerical and symbolic solutions
- for scalar, vector, and simultaneous Differential Equations. Symbolic
- and numerical solutions of state space matrix differential and
- difference equations. Over 200 algebra operations, including 3
- powerful complex-coefficient polynomial root-solvers. Over 50 data
- editing, sorting, windowing, clipping, and peak and valley analysis
- commands. Numerical differentiation and integration. Solves a 40 x 40
- system of linear equations in under 4 minutes! - $139.95"
