Math test paper for placement examination
Some multiple-choice questions are adapted from calculation questions, application questions, proof questions and judgment questions. This kind of problem can directly proceed from the conditions of the problem, use known conditions, related formulas, axioms, theorems and rules, and draw correct conclusions through accurate operation, rigorous reasoning and reasonable verification, so that the method of selecting branches is called direct method. This solution is the most commonly used. In solving problems, we should also pay attention to the flexibility of combining the characteristics of options, pay attention to the implicit conditions of the topic, and strive for less calculation. This can save time and improve the hit rate.
How to review mathematics well and understand the most basic theorems and formulas accurately
Pay attention to "accuracy" and "understanding". Therefore, the most suitable tool at this time is the textbook. When memorizing theorems and formulas, you can first understand their derivation process, and then know how the formula came from, and then do an example under the formula and apply the formula to the topic instead of rote memorization.
