About this app
Math Formula Notes is a dictionary of formulas organized to help you understand high school math formulas starting from "why they work that way."
For each formula, it includes the meaning of the symbols, the derivation process, representative examples, common mistakes, and CSAT question types.
■ Based on the 2022 Revised Curriculum
Organized like a textbook in the order of Subject › Unit › Formula.
Importance (Essential · Frequent · Advanced) is indicated for each formula, allowing you to select and view only the formulas you need within a unit.
■ Diverse Analysis of a Formula
• Meaning of Symbols: What the letters in the formula represent and what conditions are attached
• Derivation Process: Follow the steps to see how the formula is derived
• Representative Examples: Solve the problem first and check the solution
• Common Mistakes: Identify areas prone to errors in the exam in advance
• Related Formulas: Jump directly to special cases, generalizations, and commonly used formulas
• CSAT Question Types: See how this formula is used in the CSAT
■ Recall with Covers
Recall the formula first while covered, then tap to verify.
**Math Formula Notes** ■ My Formula Notes
• Favorites: Gather frequently used formulas
• My Notes: Write down teacher tips and confusing points for each formula
• Formula of the Day: Lightly review one formula every time you open the app
■ Accurate Formulas
Prompts formulas in the same format as those found in textbooks.
All formulas have undergone verification by comparing the results with calculations using different methods with random values.
■ Lightweight and Safe
• Use immediately without signing up or logging in
• Favorites and notes are stored only on your phone and can be transferred to a new device via Android backup
• There are no ads on the formula study screen
■ Current Coverage
• Algebra: Exponential and Logarithmic Functions, Trigonometric Functions
• Middle School Math: Pythagorean Theorem
Other subjects and units will be continuously added through updates.
