Parametrization 2D

Use the slider t or the run-button to move the point A along the path in 2D.
The application shows the three following vectors:
r  : Position      Red   - r(t) = [x(t),y(t)] = [f(t),g(t)]   
v  : Velocity      Blue  - The derivative of the position vector
a  : Acceleration  Green - The derivative of the velocity vector



The r-vector = [f(t),g(t)] can be changed,
the same of the minimum/maximum of the parameter t

The scale-slider can be used to adjust the length of the velocity and acceleration.



Try these parametric curves:
r(t) = [x(t),y(t)] = [5cos(t),5sin(t)]
r(t) = [x(t),y(t)] = [5cos(t),3sin(t)]
r(t) = [x(t),y(t)] = [t,t]
r(t) = [x(t),y(t)] = [2t,2t]
r(t) = [x(t),y(t)] = [t,0.5t2]
r(t) = [x(t),y(t)] = [t,sin(t)]
r(t) = [x(t),y(t)] = [3(t-sin(t),3(1-cos(t)]
