Derivative Calculator Level 1 1.0.0.0

A handy, fast, reliable, precise tool if you need to find symbolic and numerical derivatives of standard functions. Derivative Calculator Level 1 is programmed in C#. All calculations are done in double floating data type. The calculator calculates derivatives of high orders of standard functions (except hyperbolic). Calculation history can be stored into text file or printed. Numerical coefficients and values are calculated with precision 14-16 digits. Trigonometric, exponential, logarithmic, and inverse functions. Obtained symbolic formula can be used with Graphing Calculator 2D 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.
