Hi everyone, I'm just wondering if there's a list of essential math equations or a cheat sheet I should be familiar with for the SAT Math section? If so, can you share any resources or advice? Thanks in advance!
Hi there! While the SAT does provide a reference sheet with some basic math formulas during the test (mainly geometry-related), it's still a good idea to be familiar with other essential equations and concepts to help you perform at your best. Here are some key formulas and concepts you should know for the SAT Math section:
1. Area and circumference formulas for circles:
- Area = πr²
- Circumference = 2πr
2. Area formulas for triangles, rectangles, and trapezoids:
- Triangle = (base × height) / 2
- Rectangle = base × height
- Trapezoid = (base1 + base2) × height / 2
3. Quadratic formula for solving quadratic equations:
- x = [-b ± √(b² - 4ac)] / 2a
4. Pythagorean theorem for right triangles:
- a² + b² = c²
5. Slope-intercept form of a line:
- y = mx + b
6. Distance formula for finding the distance between two points:
- Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
7. SOHCAHTOA for trigonometry (within the context of right triangles):
- Sine (sin) = Opposite / Hypotenuse
- Cosine (cos) = Adjacent / Hypotenuse
- Tangent (tan) = Opposite / Adjacent
While these formulas are certainly important, remember that the SAT Math section also tests your understanding of various math concepts, so make sure to review algebra, geometry, and basic statistics, probability, and functions. Practice problems from official SAT practice tests and other reputable sources can help you solidify your understanding of these concepts and familiarize yourself with how they may be tested on the SAT.
