摘要
在概率统计教学中,强调积分式的概率意义,进而利用其求解题目,可以有效避免繁杂的变量替换、分部积分等积分运算,同时也有利于学生对密度函数性质、期望、方差、卷积公式等重要概念和公式的理解和记忆.
This paper presents a new meanings of some integral formulas. idea in teaching Probability ;and Statistics. emphasize the probability It can avoid tedious substitution of variables and integration by parts in the integral processing. It will also help students to deeply understand the concepts of probability density function,, expectation, and variance etc.
