[list][br][*] Edit the functions of t in the input boxes above for x and y.[br][*] Powers: Use t^2 for [math]t^2[/math] or t^(1/2) for [math]\sqrt{t}[/math], etc.[br][*] Use functions sin(), cos(), tan(), exp(), ln(), abs().[br][*] Adjust the range of values for which t is plotted. For example to plot [math]0\le t \le 2\pi[/math] type [math]t_{min} = 0[/math] and [math]t_{max} = 2*pi[/math].[br][*] Use the slider to trace the curve out up to a particular t value.[br][*] You can zoom in or out, add points or lines using the menu buttons.[br][/list][br][br]I'll try and add a drop down menu with the equations of some famous curves in the future...,.
