🎯 Why You Need an SAT Math Formula Sheet
While the SAT provides a few formulas during the test, many crucial equations aren’t given. Memorizing and understanding these will help you:
- Save time on test day
- Avoid careless mistakes
- Solve complex questions faster
This guide simplifies the essential formulas for you — section by section.
🧮 1. Algebra Formulas
Linear Equations
- Slope formula: ( m = \frac{y_2 – y_1}{x_2 – x_1} )
- Point-slope form: ( y – y_1 = m(x – x_1) )
- Slope-intercept form: ( y = mx + b )
Quadratic Equations
- Standard form: ( ax^2 + bx + c = 0 )
- Quadratic formula: ( x = \frac{-b \pm \sqrt{b^2 – 4ac}}{2a} )
- Vertex form: ( y = a(x – h)^2 + k )
Exponents & Radicals
- ( a^m \times a^n = a^{m+n} )
- ( (a^m)^n = a^{mn} )
- ( a^{-n} = \frac{1}{a^n} )
- ( \sqrt{a^2} = |a| )
📐 2. Geometry Formulas
Triangles
- Area: ( A = \frac{1}{2}bh )
- Pythagorean Theorem: ( a^2 + b^2 = c^2 )
- 30°-60°-90° triangle: sides = ( 1 : \sqrt{3} : 2 )
- 45°-45°-90° triangle: sides = ( 1 : 1 : \sqrt{2} )
Circles
- Area: ( A = \pi r^2 )
- Circumference: ( C = 2\pi r )
- Arc length: ( L = \frac{\theta}{360} \times 2\pi r )
Rectangles & Squares
- Area: ( A = lw )
- Perimeter: ( P = 2(l + w) )
📊 3. Coordinate Geometry
- Distance: ( d = \sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2} )
- Midpoint: ( M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) )
- Equation of a circle: ( (x – h)^2 + (y – k)^2 = r^2 )
🔺 4. Trigonometry Basics
- ( \sin \theta = \frac{\text{opposite}}{\text{hypotenuse}} )
- ( \cos \theta = \frac{\text{adjacent}}{\text{hypotenuse}} )
- ( \tan \theta = \frac{\text{opposite}}{\text{adjacent}} )
- Pythagorean identity: ( \sin^2 \theta + \cos^2 \theta = 1 )
📈 5. Statistics & Probability
- Mean = ( \frac{\text{sum of data}}{\text{number of data points}} )
- Probability = ( \frac{\text{favorable outcomes}}{\text{total outcomes}} )
- Slope of best-fit line ≈ correlation between variables
📏 6. Volume & Surface Area
| Shape | Volume | Surface Area |
|---|---|---|
| Cube | ( s^3 ) | ( 6s^2 ) |
| Rectangular Prism | ( lwh ) | ( 2(lw + lh + wh) ) |
| Cylinder | ( \pi r^2 h ) | ( 2\pi r(h + r) ) |
| Cone | ( \frac{1}{3}\pi r^2 h ) | ( \pi r(r + l) ) |
| Sphere | ( \frac{4}{3}\pi r^3 ) | ( 4\pi r^2 ) |
