# Math for Technology Suite

The Math for Technology Suite is a set of ten apps that show you how branches of mathematics such as linear algebra, trigonometry and complex numbers are applied to solve problems in technologies such as electrical, mechanical and structural engineering. To get you started, each app comes with a help file that explains how it works and with sample files to try the app out on.

Click on an app’s name to go to a web page with more details:

• Gauss-Jordan Elimination App
You type in a system of 2, 3, or 4 linear equations. Then you apply elementary row operations to solve the system. • Truss Analysis App
You draw a truss and the app sets up and solves the system of equations for the forces in the members and supports. • Nodal Analysis App
You draw a DC electric network and the app shows the nodal voltage equations and solutions.  • DC Loop Analysis App
You draw a DC electric network and the app shows the loop current equations and solutions. • AC Loop Analysis App
You draw an AC electric network and the app shows the loop current equations and solutions. • Simplex Wizard
You enter the objective function and constraints for a linear programming problem. Then the wizard helps you optimize the objective function using the simplex method. • Differentiation and Integration Visualization App
You draw a curve freehand or select one of several pre-defined curves. The app shows visually the meaning of its derivative, integral, or area under the curve. • Complex Calculator
This is a calculator with a stack that displays complex numbers in both rectangular and polar form. • Vector Tutorial
This interactive tutorial explains resolving vectors, adding and subtracting vectors, and rectangular/polar conversion. • Rotating Vectors and Sinusoidal Waveforms Tutorial
This interactive tutorial uses animation to explain how waveforms are generated by rotating vections. It explains amplitude, frequency, phase, and waveform addition.
