A vector that represents the instantaneous acceleration of a particle moving along a parametric curve (x(t), y(t)); in coordinates, the acceleration vector is
(x''(t), y''(t)) |
A curve consisting of the points (x(t), y(t)), where t varies over an interval or over the set of real numbers.
The graph of a function in polar coordinates, i.e. the points [r(θ), θ] for all θ in the domain of the function r(θ).
A vector that represents the instantaneous velocity of a particle moving along a parametric curve (x(t), y(t)); in coordinates the velocity vector is
(x'(t), y'(t)) |
