Hey guys, I've started prepping for the SAT and I'm sort of stuck on the math section. Is there a comprehensive list of SAT math formulas that I can reference while studying? Appreciate the help!
Absolutely, I can provide you with a general list of some of the important formulas and concepts you should know for the SAT Math sections. This isn't by any means exhaustive, but it's a good place to start.
Algebra and Functions
1. Slope formula: m = (y2 - y1) / (x2 - x1)
2. Slope intercept form of a line: y = mx + b
3. Quadratic equation: ax² + bx + c = 0
4. Quadratic formula: x = [-b ± sqrt(b² - 4ac)] / (2a)
Geometry and Trigonometry
1. Area of a rectangle: A = lw
2. Area of a triangle: A = 1/2bh
3. Pythagorean theorem: a² + b² = c²
4. Area of a circle: A = πr²
5. Circumference of a circle: C = 2πr
6. Definition of sine, cosine, and tangent for right triangles: sin(theta) = opposite/hypotenuse, cos(theta) = adjacent/hypotenuse, tan(theta) = opposite/adjacent
Statistics and Probability
1. Mean: sum of items / number of items
2. Probability: successful outcomes / total outcomes
Systems of equations, knowledge of functions, and understanding of exponential growth/decay are also important to have down.
Try to understand not only the formulas but also why and where you use each one. This will help a great deal in tackling the problem solving and data analysis questions, which make up about 28% of the SAT Math section. Practice is key. The more you familiarize yourself with the application of these formulas through practice problems, the better you'll fare.
Good luck on your prep!
