二项式定理的概念性比较强,并且容易混淆,同学们往往因概念不清而致误.下面举例加以分析.一、对二项式定理的公式掌握不牢例1 C_(10)~1-2C_(10)~2+2~2C_(10)~3-…+(-1)~(k-1)2~(k-1)C_(10)~k+…-2~9C_(10)~(10)的值为()。
The concept of binomial theorem is relatively strong and easily confused, students are often confused by the concept of confusion. The following examples to be analyzed. First, the formula for the binomial theorem is not firmly mastered 1 C_ (10) ~ 1 -2C_10 to 2 + 2 to 2C_10 to +3 to +10 (-1) to (k-1) 2 to (k-1) C_10 to k + ~ (10) the value of ().
