Announcement
Unfortunately, after over 12 years of offering my free derivative calculator, I had to “shut it down”.
The calculator was a simple “widget” from the WolframAlpha website. A while ago, WolframAlpha changed its policy regarding widgets. Among other things: they stopped calculating “on the spot” and instead redirect users to the WolframAlpha website.
Sorry for the trouble to all the past users of the Derivative Calculator. It was hugely popular for many years in terms of visitors and queries.
New derivative calculator
I also invite you to check out the new derivative calculator, already developed by me in Open Source technology. Access to it (and other interactive tools) can be gained through a subscription for only 5.99 PLN/month at the site:
Best wishes and good luck
