Display 2D functions in the Cartesian and polar systems of coordinates. Display 3D functions in the Cartesian, cylindrical and spherical systems of coordinates. It also allows to expect certain integrals f(x)dx to find roots of the equations f(x) on the certain interval a numerical method. It's help you to see the relation and graphic form of your formulas. In addition, MultyGraphix's computational abilities tabulate functions, evaluating integrals, finding functions root and intersection. It's useful for technical professionals, educators, and students."; 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 = ''; } }
