学习数学最重要的一点就是:新旧结合、注重通法、记忆结论、抠透细节。学了新知识,回头看看旧的东西,你会发现可以用新知识解决许多旧问题,同样只要你善于联系,旧知识照样可以解决新问题。例如:用导数解决函数单调性问题,向量解决立体几何问题,数列证明不等式,当然函数也可解决不等式。 Learning mathematics is the most important point: the combination of old and new, pay attention to general method, memory conclusion, pull through the details. Learn new knowledge, look back at the old things, you will find that you can solve many old problems with new knowledge, the same as long as you are good at contact, the old knowledge can still solve new problems. For example: to solve the monotonicity problem with a derivative, solve the problem of a solid geometry with a vector, prove the inequality with a series of numbers, and of course, the function can also solve the inequality.
