This Demonstration helps to visualize the fundamental theorem of calculus. It includes the animation of a particle's motion on the
y
axis and a plot of its height as a function of time, which is the solution to the initial value problem with differential equation
ds

=v(t)
and initial condition
s(0)=
s

. You can change the particle's initial position
s
0
and its continuous velocity function
v(t)
. As the animation runs, Mathematica graphs

on the right and the accumulated area that is colored on the left; when the animation stops, the new graph shows a function that solves the corresponding initial value problem.
