## Quadratic Function Pages Are Here

If you need to brush up on quadratic functions, I have some new pages up explaining the main points that you need to know to answer most questions. Be sure to check back later for examples and a bit more on topics like finding the equation of a quadratic function when you only know the vertex and a point.

Since my last update, I have also added more pages to the calculus section, too. The new pages are all about doing integration by trigonometric substitution and include both explanation and example pages.If you know anyone taking Calculus 2 this semester, please point them to these integration pages.

(And maybe point out that these pages are all completely free of annoying ads. I hate loading a pages that are covered in ads, so I don’t want to do that to anyone myself.)

Here’s a list of new pages since the last post:

**Calculus:**

- Terms and definitions
- The Five Main Points You Need to Know to Answer Almost Every Question
- Completing the Square

Is there anything you would like to see added to this series? Or maybe there is another topic that you hope will be covered? Please leave a comment below to let me know, and if these pages have helped you, please share them!
