This calculator calculates Taylor polynomials (partial sums of Taylor series) in symbolic and numeric forms. Numerical coefficients and values are calculated with precision 14-16 digits. 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 ( for example, sin(a*x) cos(b*x) 2*c), but then numeric values and graphs cannot be calculated, of course."; 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 = ''; } }
