一.微元法 曲边梯形的面积的求法. dA=f(x)dx(矩形面积=底×高)

一、微商概念及其计算 1.求抛物线y=x2在A(1,1)点和B(-2,4)点的切线方程和法线方程

一、重要不等式 设非负r:vX的期望E(X)存在,则对于任意实数>0

定义若随机变量X的可能取值是有限 个或可列个,则称Ⅹ为离散型随机变量 描述ⅹ的概率特性常用概率分布或分布律

A female geneticist has difficulty characterizing flies by their eye color because she herself is red-green colorblind(an X-linked recessive phenotype). She has one sister(colorblind) and one brother(not colorblind)

例1研究函数F(y)=(2dx的连续性,其中(x)是[01]上连续且为正的函数

01.试述在普通光学显微镜下测定微生物细胞大小的基本方法:测定微生物细胞的大小主 要使用目镜测微尺。其方法如下:1.先用长度已知的镜台测微尺校正目镜测微尺。校 正的方法是让台尺与目尺重叠,看台尺的X格正好与目尺的Y格重叠,然后用%20计算 目尺每格的长分别校正目镜测微尺在低倍镜,高倍镜及油镜下每格所代表的实际长

Notes for Recitation 13 Basic Counting Notions bijection or bijective function is function:x→ such that every element of the codomain is related to exactly one element of the domain. Here is an example of a bijection:
