**STFMath (ex SunCalculator)**is a multipurpose math utility, suitable not only for students, but also for engineers, professors, or anyone interested in math.

**Graph Mode**

¤ Draw Cartesian, Parametric and Polar functions

¤ Draw Integral and Average

¤ Draw Derivative

¤ Evaluate functions

¤ Perform function analyze [max. min, zeros…]

¤ Calculate intersection

¤ Calculate and preview integral

¤ Calculate derivative and average

¤ Draw and calculate equation of tangent or normal

¤ Save drawn graph as an image [bmp, wmf, jpg], or copy graph to clipboard and paste in external applications

¤ Insert textual labels into the graph, print graph or graph history, adjust graph attributes

¤ Build a table of values and publish it as HTML

¤ Prepare presentation using built-in MathPad, fully functional text editor

**Calculators**

Matrix Calculator offers basic and advanced matrix calculations, with fully supported complex numbers usage. Supported operations:

¤ Matrix addition, subtraction, multiplication, scalar multiplication and division (max matrix size 50x50)

¤ Calculate determinant and trace, characteristic equation [for 2x2 and 3x3 matrix], adjoint [adjugate] and inverse matrix

¤ Matrix edition [swap matrixes, swap and delete rows or columns, multiply and submit rows and columns, transpose matrix]

¤ Edit matrix in MathPad

¤ Save/Open matrix as a Matrix calculator file

¤ Publish result as HTML

¤ Calculate solutions of linear equations system [up to 50 variables]

**Function Evaluator**- evaluate functions [incl. special function, like Gamma, Betta etc.] without limits; Evaluate X and Y points.

**Complex Calculator**offers basic and advanced complex calculations [argument, reciprocal, trigonometry and hyperbolic, exponential, logarithm…].

**Geometry Calculator**- calculate with easy: triangle, circle, frustrum, ellipsoid, draw and calculate polygons.

**Geometry Units Converter**- easily convert values for angle given in degrees [+ minutes + seconds] to radians or grads. For more extensive converting use given lists of units under Angle, Area or Distance.
