Is compulsory math 2 difficult to learn? How to learn well?
Mathematics is a compulsory course. If you use the same textbooks as us, it is mainly solid geometry and analytic geometry. In the part of solid geometry, the ability of spatial imagination is needed. I really can't think of stealing some chopsticks from the canteen as a gesture. To prove a problem, you should memorize all axioms and theorems and be able to use them flexibly, especially be familiar with the reduction to absurdity; There will be a lot of radical numbers in the calculation problem. We should have strong enough computing power and try to transform three-dimensional problems into plane problems. The common methods are making slices and making projections. Analytic geometry, especially calculation, only needs to remember a few basic equations. The discussion of solid geometry and analytic geometry in compulsory mathematics 2 is incomplete. If you are a science student, or plan to become a science student, you will study space vectors in the future, transform solid geometry into thorough calculation, and learn the knowledge of conic curves.
