Tangent Software

Graphmatica

A powerful, easy-to-use, equation plotter with numerical and calculus features: Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations. Up to 999 graphs on screen at once. New data plotting and curve-fitting features. Numerically solves and graphically displays tangent lines and integrals.

FlatGraph

Software that is a product that allows you to enter the function in a symbolic form and to display its graph. Supports taking the derivatives and parametric functions.

JustCad

This graphics utility is designed, to make cad drawing as simple as possible. To draw any object, simply click on the screen or snap to an existing object, move the cursor, in the desired direction and enter a distance. To change an angle setting for any function, simply click on it''s display box and enter a new value. Draw confined to an angle or free cursor, with a simple click on the display.

Function Grapher

Software that is an easy-to-use software for 2D, 2.5D and 3D function graphing, animation and table data visualization. 2D and 2.5D function graphs can be plotted in Cartesian and polar coordinate systems,and 3D function graphs can be plotted in Cartesian,cylindrical and spherical coordinate systems.

Harmonix

With the Harmonix PhotoShop plug-in you can create complex waveforms. The waveforms generated by Harmonix are created by mixing (or superimposing for the more technically-minded) harmonic frequencies. All features of the waveforms are automatically scaled to fit the image (or selection of course) so you will not have to reconfigure an entire wave should you decide to change the image size.

Math Studio

Math tool for high school teachers and students. Function graphing and analyzing, sequence of number, analytic geometry and solid geometry. Math Studio is licensed as shareware and filed in education mathematics section.

UltimaCalc

A calculator with minimal screen footprint and text input. See what you typed, edit it, log calculations as text file. Algebraic expressions, trigonometry, definite integrals, prime numbers. User defined functions and constants. Also Bar charts, Scatter charts, Regression (Linear, Polynomial, Multivariate, Absolute Deviation); Standard Deviation; Plot functions; Solve Triangles; Simultaneous Linear Equations; Polynomial Roots; Navigation; Dates. This shareware is listed under business calculators, converters category.

Visual Calculus

Software that is an easy-to-use software for Graphing limit, derivative function, integral, 3D vector, series, ode etc. Which can create 2D, 2.5D and 3D function graphs, animations and table graphs. 2D and 2.5D function graphs can be plotted in Cartesian and polar coordinate systems,and 3D function graphs can be plotted in Cartesian,cylindrical and spherical coordinate systems. This demo is listed under education mathematics category.

vCalc

Software that is a keyboard driven scientific calcualtor, that works using the RPN notation common in well known scientific calculators. It supports a complete set of math, binary and statistical operations. vCalc software is a shareware filed under browsing, searching, imaging utilities.

KwikTrig

KwikTrig solves for RIGHT and OBLIQUE triangles, BOLT CIRCLES, calculates SINES and COMPOUND SINES. Use decimal degrees, or degrees/minutes/seconds for input/output on all calculations on the above and rounds numbers from 1 to 15 decimal places. Also, has calculations for inscribed/circumscribed POLYGONS. GEOMETRY allows user to plot circles, points and lines, finds the INTERSECTIONS of those lines.

iota-calc

An all purpose scientific calculator, designed with programmers in mind. - Supports a rich expression format, which is in most cases identical to what you would type in your programming language. - Support for adding unlimited numbers of variables or variable expressions. - Built-in debugger that lets you see the expression simplified step by step. - Many more features.

Silhouette PlugIn

Silhouette is a plugin for Adobe Illustrator 8, 9 and 10 to convert bitmap images to vectors images with unique correction tool * vectorizes colors and b&w images/logos * straightens up a logo * sharpens rounded or truncated corners * deletes useless points * converts flat curves into straight lines * aligns segments of straight lines on the same axis * smoothes curves * simplifies curves while keeping their appearance

STFMath

This software, technically enhanced math utility, allows you to: draw Cartesian (standard or parametric) and Polar functions, special functions (Gamma,Beta,Fourier, Blancmange) or Integral (with Average preview) in MDI (Multi Documents Interface) supported Graph Mode (open up to 10 independent graph documents in the same window).
