摘要
利用定积分几何意义揭示定积分积分区间可加性;以一次函数为例揭示积分上限函数是被积函数的原函数;用几何方式解决一些特定积分的求法。以更直观,学生易接受的方式训练学生多角度思考问题。
It reveals that the integral interval of definite integral may be additive by using the geometry meaning definite integral. It reveals that the integral upper limit function is the original function of the integrand by linear function. It explains some methods of specific integral in geometry. It expounds how to train students to think more in a more intuitive, easy acceptable manner.
