fx-Calc is an advanced calculator that allows straightforward and intuitive handling of complex mathematical tasks.It lets you define, analyze, visualize and calculate scientific functions and is a full-featured replacement and enhancement of the old fashioned Windows calculator. In addition to calculation and visualization, you can analyze and solve scientific functions and perform linear regression. Even if the Window concept may not look advanced, it provides the big advantage of opening similar windows multiple times to compare the results as needed.fx-Calc also includes an editor field for inputting the sums, etc., which you would like to calculate. All calculations are done in real time with results being provided as you type. In the event, you make an error, fx-Calc displays that text in red and will display an error message allowing you to redo your work. fx-Calc Features: definition and immediate calculation of functions with up to 5 variables solves equations function analysis combined with graphic result presentation - roots, extreme - and pole points, integration tangent calculation and interactive Newton iteration parametric sum and product calculation an integrated function library integrated library for scientific constants 2D function plots including complex graphs 2D parametric function plots OpenGL accelerated 3D function plots multiple plot and analysis windows to compare different function characteristics interactive linear regression module assistant for combinatorics automated history displays current memory value in a separate field integrated examples handling complex numbers syntax highlighting
