Calculus is divided into differential and integral, and differential is derivative. As far as Beijing college entrance examination is concerned, derivative is generally the penultimate question in the whole college entrance examination, which is a difficult problem. This question is generally two questions. The first question is generally derivative, which is relatively simple, and the second question is slightly more difficult. This problem is generally discussed in categories. Many students lose points because the classification is not comprehensive or even they don't know how to classify at all. Integral is relatively simple. Generally, one or two points will be obtained directly, which is a relatively simple question type, but it has not been tested in the college entrance examination in the last two years. I wonder if 20 12 will take the exam?
