Good question, but the thing is that there is no API for the website. You usually use an HTTP API to send requests and get responses for the request. Apart from this, you are more likely to get your request's status CANCELLED because of CORS; cross-origion resource sharing.

There is however one thing that you can do, at the end of the website author has shared his email address. You can contact him to ask for a way, he might create an API for you (and other developers with same opinion and need). Then you can send requests to the website with some expression and get the results.

Do you know any other way to calculate integral easily with C#?

Nope, there is no easy way to calculate integrals in C#. Integrals is pure calculus, C# is just the language you use to talk to .NET framework or other similar platforms. You would have to make the framework understand how to do, how to do. Would that be easy enough? (No, in my opinion).
