How to use the tool

The use of this tool is quite similar to the Function Calculus Tool. Key in the functions x(t) and y(t) in the the cells B5 and B6 respectively. The equal to sign must be used so that the cells display the value corresponding to t = min(t).Key in the range of t in the cells B10 and B11.

For example, to plot the curve given by x(t) = sin(t) and y(t) = cost(t), the screen would look like this if the entries are made correctly. These equations are the parametric equations of a circle. The entire circle is plotted if the range of t equals or exceeds 2*pi, otherwise a part of the circle is plotted.
