Math Equations and the ACT

Hey fam, anyone have a list or guide to the kinds of math equations I'll need to know for the ACT? I would really appreciate some help brushing up.

Sure, I can definitely help guide you on that! The ACT covers Pre-Algebra, Elementary Algebra, Intermediate Algebra, Coordinate Geometry, Plane Geometry, and Trigonometry. Here are some major topics you might encounter:

1. Algebra: Know everything from basic operations to quadratic equations - factoring polynomials, solving linear equations and systems of equations, interpreting expressions, dealing with inequalities, solving quadratic equations, etc.

2. Geometry: Understanding of shapes and their properties will be key. Be comfortable with triangles (especially right-angled ones), circles, and polygons, and be familiar with properties of parallel and perpendicular lines, circumference, area, volume, etc.

3. Trigonometry: You'll need to understand sine, cosine, tangent, their relations, and how to use them in right triangles.

4. Probability and Statistics: This includes median, mode, mean, range, probability of an event, etc.

5. Coordinate Geometry: Understand slopes of lines, midpoints, distance, graphing equations, etc.

6. Arithmetics: Ratios, proportions, complex numbers, and absolute values are all within the realm of arithmetic operations tested on the ACT.

7. Functions: Understanding and interpreting functions is a must. This could include operations with functions, range/domain considerations, inequalities, etc.

For a deeper dive, the ACT website offers a comprehensive math practice section that breaks down these topics even further. Remember, practice goes a long way! Good luck with your prep!
