Ability to create color map, contour plot and vector plot. Ability to move, zoom in, zoom out and rotate graphs. Ability to save graphs as pgp file or bmp file. Ability to save animation as AVI file.

A handy, fast, reliable, precise tool if you need to find symbolic and numerical Taylor polynomials of standard functions. Taylor Calculator Real 36 is programmed in C#. All calculations are done in double floating data type. The calculator calculates partial sums of Taylor series of standard functions (including hyperbolic). Calculation history can be stored into text file or printed. Numerical coefficients and values are calculated with precision 36-45 digits. Trigonometric, exponential, logarithmic, hyperbolic, and inverse functions. Obtained symbolic formula can be used with Graphing Calculator 2D Polar, Graphing Calculator 2D Parametric, and Graphing Calculator 2D Numeric for drawing graphs. There is also possibility to use symbolic parameters.

A handy, fast, reliable, precise tool if you need to find symbolic and numerical derivatives of standard functions. Derivative Calculator Real 36 is programmed in C#. All calculations are done in proprietary data type. The calculator calculates derivatives of high orders of standard functions (including hyperbolic). Calculation history can be stored into text file or printed. Numerical coefficients and values are calculated with precision 36-45 digits. Trigonometric, exponential, logarithmic, and inverse functions. Obtained symbolic formula can be used with calculators Precision series, and with Graphing Calculator 2D Parametric, Graphing Calculator 2D Polar, and Graphing Calculator 2D Numeric for drawing graphs. There is also possibility to use symbolic parameters. For example, sin(a*x)+cos(b*x)+2*c.
