James Stewart's calculus texts are widely renowned for their mathematical precision and accuracy, clarity of exposition, and outstanding examples and problem sets. Millions ...

This best-selling text by these well-known authors blends the traditional algebra problem solving skills with the conceptual development and geometric visualization of a ...

Two related packages, Ricci and Tetrad, can be used to compute the basic geometrical quantities appearing in the field equations of general relativity. The first is meant for ...

A three-dimensional anisotropic super micro-etching of crystalline silicone in aqueous KOH is simulated on an atomic level using a new three-dimensional cellular-automata ...

The analytic method for plotting root loci is examined. The basic equation for this method, originally published by Bendrikov and Teodorchik in 1959, is derived in a very ...

Analytic solutions for limiting forms of the nonlinear Schrödinger equation are presented for dual-frequency input pulses propagating through single-mode, ...

The two-dimensional wave motion caused by a circular ring and elliptic ring impulsive source is studied with respect to the geometric shape of the wave fronts and features of ...

Symbolic algebra languages offer an exciting opportunity for the development of online teaching aids which are closer to textbook format. Some of the facilities developed to ...

The paper presents an approach of tuning PID controllers using integral criteria and symbolic calculus facilities as offered by one of the most powerful symbolic calculus ...
