UltimaCalc Professional is a highly functional graphing math toolbox with a compact and intuitive design offering the ultimate balance of power and convenience.
Its algebra module lets you perform manipulations and simplifications on basic and complex algebraic expressions. UltimaCalc lets you do calculus: differentiate an expression, or find its integral and ask how this was found.
You can factorise polynomials, multiply and divide one polynomial by another, find the GCD of two polynomials. Expand and contract trig expressions. Calculate Taylor series, define your own functions, and calculate exact results (try evaluating the factorial of 1000).
Other modules let you fit lines or curves to your data (5 methods), find the values of variables that minimise an expression, plot functions (including parametric plots), find the roots of polynomials, solve simultaneous linear and non-linear equations, calculate standard deviations and other statistics, solve triangles, create graphs and charts.
UltimaCalc is designed for usability. The main window is a calculator with an amazing 38 digits of precision. You can make the window transparent when inactive so you can read a document underneath it. You can hide the title bar. Keep the calculator open all the time, on top of other windows, always ready for use, or use hot keys to instantly hide and restore it.
Define your own functions, use them just like the built-in functions, and build up a library of them. Define your own constants, too.
Choose how many digits to display, and show them grouped in sets of three or five digits. Full support for hexadecimal numbers and complex numbers.
Log all calculations to a text file, and copy and paste calculations to other applications as plain text.
Contains a handy reference table of more than 300 constants, including atomic weights.
Comprehensive help (with index) is provided for all features.

Manipulate algebra. Integrals found & explained. Define own functions and constants. Find Standard Deviation etc. Plot functions. Solve Triangles. Least Squares fits, inc. nonlinear, Simultaneous Linear/Nonlinear Equations. Polynomial Roots. More.
Pros: This program too has a unusual approach to the interface. This is really a single line entry window to leave the screen free for other use. Additionally, this window can be partially transparent when inactive, so you can read documents open underneath it. It is a collection of mathematical tools in one program, for use by scientists, engineers and students. The main window is a calculator that accepts mathematical expressions as plain text and evaluates them to 38 digit precision. The symbolic algebra module helps simplify expressions, differentiate them, and integrate a range of expressions and so on. Finding Taylor series, factorizing polynomials, division of polynomials etc are things that can be done easily.
Statistical analyzes like standard deviation, finding mean/median/skewness, of a dataset is easily done with the functions available. These allow linear regression or polynomial fitting are also features of this set of functions. Analyzing a set of measurements and approximating complex functions with simpler curve fitting is also possible with the calculator. Multivariate analysis is also possible. Solving non linear equations is assisted by root finding, solving of triangles etc.
The calculator also facilitates plotting of arbitrary functions when starting and end conditions are specified, up to 8 such plots can be combined. Recording of history and storage of curves as images for future reference provide support to all of the above.
Cons: Effective use of the calculator would need training in the specific areas of functionality. Not all functionality thus can be used by any one group of users who may not have training in other areas. But then these are specialized functions anyway.
Overall: This is a full featured application for useful calculations required by specialized groups of people. This is at the 4 star level quite easily.
