| # SAT Math Formula Sheet |
|
|
| The 24 formulas and concepts the SAT does not give you on its reference sheet. |
|
|
| The digital SAT provides a reference sheet on every math question with area, |
| circumference, volume and right-triangle formulas. It does not provide slope, |
| the quadratic forms, the discriminant, exponent rules, percent change, |
| exponential growth, probability, or the circle equation. These 24 cover what it |
| leaves out. |
|
|
| ## Contents |
|
|
| `formulas.json` holds 24 records: |
|
|
| | field | meaning | |
| | --- | --- | |
| | `n` | position on the sheet, 1 to 24 | |
| | `slug` | stable identifier | |
| | `title` | name of the concept | |
| | `domain` | one of the four College Board domains | |
| | `skill` | College Board skill name | |
| | `formula` | the notation, one string per line; empty for the three that are concepts rather than equations | |
| | `note` | one-line reading of the formula | |
| | `keyPoint` | what the SAT actually tests on it, and the usual trap | |
| | `url` | full explanation with a solved SAT question | |
|
|
| Three of the 24 are concepts rather than equations (Quadratic Interpretations, |
| Standard Deviation, Similar Figures) and carry an empty `formula` list with the |
| point they test in `keyPoint`. |
