What are the courses involving analytic geometry in senior high school mathematics?
Test center: straight line (the most basic, almost all questions will be involved) conic curve (ellipse is the most important, followed by hyperbolic parabola) circle (in order to avoid conic curve rotting, there are circles in the college entrance examination for several years, so we must pay attention to the use of plane geometry when taking the round exam)

Methods: Definition (the first and second definitions of conic curve are often very important, which is often the breakthrough of objective problems) is not required (used for conic curve, which requires high technology) and the application of plane geometry (similarity, parallelism and midline). . . . . . ) Parametric equation (sei ta is used to represent x y in an ellipse) Polar coordinate form of point difference conic curve of D-Etta theorem (Jiangsu 20 12 college entrance examination is easy to analyze geometric problems) Dead algorithm (some people can't be experts, but their computing ability is poor, in fact, 70% of so-called problems can be decoded by hardware) Equation thought vector intersection method and so on. . . . . . .

Analytic geometry in high school is a hard bone, and it is also the key and difficult point in high school. Some people have made great efforts, but in the college entrance examination, they only got 5 or 6 points in 16 because they missed an unpopular knowledge point. It can be said that few people are absolutely sure to make analytic geometry questions in the college entrance examination (especially in our big Jiangsu).

Beginners are advised to start with different shapes of various curves (such as straight line is a little oblique, intercept type, two-point type, oblique section type, general type, etc.). ), master the different uses of various forms, and then deeply understand the topic.

There is also a conscious exercise of their computing power. Analytic geometry problem is half calculated, which is good. Even if the method is flawed, they are sure to make it. However, some people do not attach importance to or even ignore calculation. They think it's okay to have a good idea and don't want to plot them. This is completely wrong.

I think so much for the time being, I hope it will be useful to you.
