Unfortunately, after over 12 years of providing a free function limits calculator, I had to “turn it off”.

The calculator was a simple “widget” from WolframAlpha. Recently, WolframAlpha changed its policy regarding widgets. For example: they no longer calculate “on-site” and instead redirect the user to WolframAlpha.

I apologize to all past users of the Function Limits Calculator for the inconvenience.

New Function Limits Calculator

I also invite you to the new function limits calculator that I created using open-source technology. Access to it and other interactive tools is available through a subscription for just 5.99 PLN/month (or cheaper with multi-month options) on the website:

And the calculator itself looks like this:

Best of luck!
