一、偏导数的定义 1.偏导数定义 定义1设f(x,y)是一个二元函数,定义在R2内某一个开集D内,点(x,yo)∈D,在f(x,y)中 固定y=yo,那么f(x,yo)是一个变元x的函数,如果f(xy)在点x可导,即如果

我们希望能够找到一种方法,能够从任意一个n阶线性定常的 般形式的微分方程组中构造出一个n维的状态空间模型。设输出量a (标量)与输入量r(标量)之间的关系由线性定常微分方程表示。 我们定义状态量为ω及其n-1阶导数 这样,我们就得到了n个状态量(与微分方程的阶次相同)。现 在我们对x求导,直到x(n-1)

Player i is rational\;R=nieN Ri. Also, Bi(E) is the event \Player i is certain that E is true\ and B(E)=neN Bi(E). This is as in Lecture 7. Let me introduce the following notation for iterated mutual certainty: B()(E)=E B()(E)=B(B-I)(E)). Then the definition of Bk in Lecture 7 can be rewritten as Bk
