Does anyone know of any online free ACT Math Cheat sheet or formula sheets? I don't want to use them to cheat when I'm taking the test, I just want all the formulas in one place for when I'm studying.

**Yes, we have an article about it on the PrepScholar blog**: "The 31 Critical ACT Math Formulas You MUST Know". While the formulas aren't all in one printable sheet, they are all in one article, so you can just copy + paste the formulas themselves into a separate document for use while studying - and use the article for information on when each formula is useful.
