2GRE數(shù)學(xué)詞匯總結(jié)
對(duì)于準(zhǔn)備參加GRE考試的考生來說，掌握數(shù)學(xué)相關(guān)的詞匯是非常重要的,。數(shù)學(xué)詞匯不僅在考試中頻繁出現(xiàn),，還能幫助你更好地理解題目和解題思路。以下是一些關(guān)鍵的數(shù)學(xué)詞匯及其解釋,，希望能幫助你在備考過程中更加得心應(yīng)手,。
1. Basic Terms (基本術(shù)語)
- Integer (整數(shù)): A whole number that can be positive, negative, or zero. For example, -3, 0, and 5 are integers. ??
- Fraction (分?jǐn)?shù)): A numerical quantity that is not a whole number, represented by one integer divided by another. For example, 1/2 or 3/4. ??
- Decimal (小數(shù)): A fraction whose denominator is a power of ten, expressed using a decimal point. For instance, 0.75 or 3.14. ??
2. Algebraic Expressions (代數(shù)表達(dá)式)
- Variable (變量): A symbol used to represent an unknown number in mathematical expressions, commonly denoted by letters like x or y. ??
- Coefficient (系數(shù)): A numerical factor in a term of an algebraic expression, such as 3 in the term 3x. ??
- Equation (方程): A statement that two expressions are equal, often containing variables. For example, 2x + 3 = 7. ??
3. Geometry Terms (幾何術(shù)語)
- Angle (角): The figure formed by two rays, called the sides of the angle, sharing a common endpoint. Angles are measured in degrees. ??
- Perimeter (周長(zhǎng)): The total distance around a two-dimensional shape. For example, the perimeter of a rectangle is calculated as 2(length + width). ???
- Area (面積): The measure of the amount of space inside a two-dimensional shape, typically measured in square units. For instance, the area of a rectangle is length × width. ???
4. Data Interpretation (數(shù)據(jù)解讀)
- Mean (平均值): The sum of a set of numbers divided by the count of numbers in the set. It represents the average. ??
- Median (中位數(shù)): The middle value in a list of numbers sorted in ascending order. If there is an even number of observations, the median is the average of the two middle numbers. ??
- Mode (眾數(shù)): The value that appears most frequently in a data set. It is useful for understanding trends in data. ??
5. Probability and Statistics (概率與統(tǒng)計(jì))
- Probability (概率): A measure of the likelihood that an event will occur, ranging from 0 (impossible) to 1 (certain). For example, the probability of flipping a coin and getting heads is 0.5. ??
- Sample (樣本): A subset of a population used to represent the entire group in statistical analysis. ??
- Hypothesis (假設(shè)): A proposed explanation for a phenomenon, which can be tested through study and experimentation. ??
Practice Makes Perfect (練習(xí)使完美)
To reinforce your understanding of these terms, consider practicing with sample questions. Here’s an example:
Example Question: If the mean of five numbers is 20, what is their total sum?
Answer: The total sum is 20 × 5 = 100.
Regularly revisiting these concepts and testing yourself with practice problems can greatly enhance your performance on the GRE. Also, try to incorporate these terms into your study routine, helping you become more comfortable with both the vocabulary and the underlying mathematical concepts.
Final Thoughts (最后的思考)
As you prepare for the GRE, remember that familiarity with mathematical vocabulary is crucial. Not only does it help you understand the questions better, but it also aids in articulating your thought process when tackling complex problems. Good luck with your studies! ??
