How to reach Continuous Function.

• A correction: the page address, the sentence, equation or figure, what you think is wrong and, if you have one, a source.
• A question about the curriculum: which notebook or investigation it is about, and what you expected to see.
• Research collaboration: the question you have in mind and what you would bring to it.
• An accessibility problem: which page, what you were trying to do and, if you are willing, what you use to browse. The accessibility statement lists the problems already known.
• A security problem: what you found and how to reproduce it. Please report it privately to this address rather than in public; the site’s security.txt file gives the same address.

Corrections are welcome, small or large. The site teaches mathematics and states what its results do and do not show, so an error in either matters.
