How to use
The text input fields can accept a wide variety of expressions to represent functions, and the buttons under the graph allow various manipulations of the graph coordinates.
Examples
Line:
x1(t)=t-1
y1(t)=1-t    
Circle:
x1(t)=cos t
y1(t)=sin t    
Polar curve:
x1(t)=cos 5t cos t
y1(t)=cos 5t sin t    
Cycloid:
x1(t)=t-sin t
y1(t)=1-cos t

Other Notes
The bounds tmin and tmax apply to all functions graphed.
