Mathematica notebooks for differential equations keyed to the textbook "Fundamentals of Differential Equations, Third Edition" by R. Nagle and E. Saff, Addison-Wesley, ...

Mathematica continually improves as a program. Part of that improvement often involves moving items from add-on packages to core programming. The packages rendered obsolete ...

The Laplace transform is often applied to linear partial differential equations to eliminate the time dimension. The analytical solutions thus obtained need to be inverted to ...

Many vibration problems in engineering are nonlinear in nature. The usual linear analysis may be inadequate for many applications. An essential difference in the study of ...

A new two-parameter descriptive model for the size distribution of incomes is presented. The Beaman distribution, originally found to describe the relationship between prices ...

The cargo loading problem is a special type of integer programming or optimization problem which can easily be solved by dynamic programming. The problem is explained in ...

Mathematica contains all linear algebraic tools necessary for working in Euclidean Geometry. The notebook "Euclidean Geometry" shows these tools and some variations of them ...

The program demonstrates convolution by graphic examples. The user creates the input signal and convolutional kernel graphically using the mouse rather than typing in a ...

This notebook illustrates the solution of four simultaneous ordinary differential equations with three constant initial boundary conditions and one algebraic final boundary ...

NONACODE is a Software Package for Analysis and Design of Nonlinear (Adaptive) Control Systems with the Differential-Geometric Approach.We consider Nonlinear Systems ...
