Announcement
Unfortunately, after more than 12 years of providing a free derivative calculator, I had to “shut it down”.
The calculator was a simple “widget” from WolframAlpha. Some time ago, WolframAlpha changed its widget policy. Among other things: they no longer calculate “on-site” but redirect the user to the WolframAlpha website.
Apologies for the inconvenience to all users of the Derivative Calculator. For many years, it broke records in terms of visitors and queries.
New Derivative Calculator
I also invite you to the new derivative calculator, created by me using Open Source technology. You can access it (and other interactive tools) with a subscription for just 5.99 PLN/month at:
And the calculator looks like this:
Best regards and good luck!
