## Main Question or Discussion Point

**I want to make an animation where a (red) ball departs from (0,0) and draws the function**##f(x) = sin x##

This is what I know:

How to plot ##f(x) = sin x##

To do so I followed instructions from the worksheet. Actually I'd have done:

But I guess they want to me to it in that way because I have to do less work while coding for the red dot to draw the entire sine curve.

Now to plot just a piece of the function:

If we set i=50 and x runs from 0 to 200, we are aiming at plotting just 1/4 of ##f(x) = sin x## .

The line ax.plot(X

*, Y*

*, 'o', color='red') locates the point at i=50 (I guess 'o' is just the command for the point).*

But now, how can I code such an animation of ##f(x) = sin x## from (0,0)? I have read I should import:

import matplotlib.animation as animation

I've been looking for exercises on animations in SymPy in Python but found nothing.

Any help is appreciated.But now, how can I code such an animation of ##f(x) = sin x## from (0,0)? I have read I should import:
