ACT test formula sheet - what should I include?

Hey guys, I'm creating a formula sheet for the ACT to help me with my studying. Can you give me some suggestions on what formulas and concepts I should include? Thank you!

Hey there! Creating a formula sheet is a great strategy for ACT prep. Here are some key formulas and concepts you might want to include for different sections of the ACT:

Math:

1. Quadratic formula: x = (-b ± sqrt(b² - 4ac)) / 2a

2. Distance formula: d = sqrt((x₁ - x₂)² + (y₁ - y₂)²)

3. Pythagorean theorem: a² + b² = c²

4. Slope-intercept form: y = mx + b

5. Midpoint formula: M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

6. Trigonometry ratios: sin(x), cos(x), and tan(x)

7. Area and perimeter formulas for basic shapes (rectangle, triangle, circle)

Science:

1. Understanding independent and dependent variables

2. Familiarity with experimental design and controls

English:

1. Proper punctuation usage (commas, semicolons, colons)

2. Subject-verb agreement

3. Pronoun-antecedent agreement

Reading:

1. Practice active reading strategies (note-taking, summarizing)

2. Identify main ideas and supporting details

Keep in mind that the ACT tests your knowledge of concepts, so it's essential to practice using these formulas and understanding the underlying principles. Good luck with your test prep!
