This is a product which can be found most useful by scientists, engineers, professors, and students.
This calculator calculates derivative functions of high orders in symbolic and numeric forms. Numerical coefficients and values are calculated with precision 45-54 digits. Obtained symbolic formula can be used with calculators Precision series, and with Graphing Calculator 2D Numeric, Graphing Calculator 2D Parametric, and Graphing Calculator 2D Polar for drawing graphs. There is also possibility to use symbolic parameters ( for example, sin(a*x) cos(b*x) 2*c), but then numeric values and graphs cannot be calculated.
All calculation results are reflected in History rich-text-box, which can be saved in file or printed."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
