Derivative Plotter
I have made a Derivative Plotter
It plots the "derivative" by simply calculating successive points and working out the slope. I can't think of a simple phrase to say that ... "calculated slope"?
But a really cool feature is at the bottom where you get to plot a function in green to (hopefully) coincide with the "calculated slope".
Comments and Suggestions pretty please!

Re: Derivative Plotter
Hi MIF;
It works well even getting the correct plot for this tough one.
You could have calculated those points using a formula instead of the slope between two points. But if the speed is acceptable that way, why change?
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Hi MathsIsFun,
The Derivative Plotter is neat. Excellent work!

Re: Derivative Plotter
hi MathsIsFun
That's great and worked well for all I tried.
There was one odd thing that happened. I suspect it's my laptop as I've had the odd thing happen with graphics before. But I'll describe what happened anyway, in case you can shed any light.
If I slide the zoom control fully left, as I start to slide back towards the centre, the graphs (everything inside the function and the slope borders) vanish. And stays that way unless I press the reset. This doesn't happen for a slide right.

Re: Derivative Plotter
Sounds like a glitch in the program ... will investigate, thanks.

Re: Derivative Plotter
New version 0.6, only minor changes, hopefully fixed the zoom bug that Bob found. (Use refresh!)

Re: Derivative Plotter
The graph of tan(sin(tan(cos(tan(x)))) and its derivative look cool!
The limit operator is just an excuse for doing something you know you can't.

Hi;
e^(sin(x)) makes nice waves.

Re: Derivative Plotter
Yes, it has fixed the zoom. Thanks.

Re: Derivative Plotter
Excellent.
e^(sin(x)) is quite nice to scroll back and forth on

Re: Derivative Plotter
Larger plot boxes and panning functionality would be nice...

You can pan by single click (re-centers image)

Re: Derivative Plotter
When I left click it gives me the selection tool so that when I let go of the mouse, it zooms into the area I selected.

Re: Derivative Plotter
I am unable to use the derivative plotter offline. I copied the swf file from temporary internet file folder and tried to play it but only blank screen. Any ideas
Thanks
