SunCalculator is easy-to-use and powerful math utility. Here are some of its features: Graph Mode? Draw any standard (Y = f (X)) or parametric function (Y = f1(K), X = f2(K)). The list of supported functions (trigonometric, logarithm, exponential, hyperbolic) is extended with predefined functions. In the same window it is possible to draw unlimited number of functions, with different attributes (scale grid, show/hide axes, graph, background and greed color, zoom level, inserted textual labels etc.)? Draw tangent or normal in any point of actual graph, calculating tangent''s equation.? Perform complete function analyze (calculate roots, critical points - maximum and minimum, Y-intersection) and edit/save function analyze log? Calculate integral (with integral preview), 1st derivative and average of drawn function? Save drawn graph as an image (.bmp, .wmf or .jpg) and insert it in built-in MathPad, fully functional text editor, or edit it in external programs (Corel, Photoshop, Word...)? Calculate table of values for specified function and publish it as HTML? Trace drawn function with simple right mouse click? Change graph''s attributes, grid options, zooming factor of plotting area, move center? Print drawn graphs or graph history Advanced Mode? Perform basic and advanced algebraic and trigonometric calculations with built-in scientific calculator. Complex Mode? Complete managing of complex numbers (incl. sin, cos, tan, sinh, cosh, tanh, power, log, argument, magnitude etc.)Evaluator? Function (expression) evaluator (for unlimited range of functions - enter expression incl. functions with arguments as a numbers and evaluate it) MathPad? MathPad - built-in text editor (paste images of drawn functions, add text with all kind of formatting and you are ready for presentation)
