STFMath, technically enhanced math utility, allows you to: string Cartesian (stock or parametric) and Polar functions, special functions (Gamma, Beta, Fourier, Blancmange) or Integral (with Average preview) in MDI (Multi Documents Interface) supported Graph Mode (loose up to 10 independent graph documents in the same window). Supported functions number (logarithm, trigonometric, exponential, hyperbolic) is protracted with predefined functions. - In the same window it is possible to string unlimited turn of functions, with different attributes (grid scaling, concentrate moving, graph colors, textual labels inserted etc.). Additional options are: - Calculate integral, derivative and norm values, and string integrals with norm preview - Calculate and string tangent and normal and trace drawn functions - Perform officiate study (figure roots, critical points, Y or two functions product), figure table of values and publish it as HTML - Evaluate any officiate or perform various additional calculations with built-in scientific, complex and geometry (with units converter) calculators - Save drawn graph as an visualise (.BMP, .WMF, .JPG), copy it to clipboard or print graphs and graph history - Build presentation with MathPad, fully functional text editor. - Use scientific, geometry, complex, geometry unit converter. - Use matrix (up to 50x50 in size, with complex numbers support) calculator with supported operations: - Matrix addition, subtraction, multiplication, scalar multiplication and division; - Calculation of matrix determinant and trace, characteristic equation (for 2x2 and 3x3 matrix), adjoint (adjugate) and inverse matrix; - Matrix edition (swop matrixes, swop and delete rows or columns, multiply and defer rows and columns, interchange matrix and more.
