Mthod of proof by cases 证明完所有的条件分支,然后得出结论. 证明任意 使用任意 注意,对于一个任意的东西,你不知道它的具体信息.比如对于任意正数,你不知道它是 1 还是 2等等. 使用矛盾 证明相反的结论是错误的 归纳法 Prove the initial step, then apply to the induction step. Prove the mathematical theorems Assignment 解析:首先尝试找到 m, n 使得结论成立.因为…
Q: Why did nineteenth century mathematicians devote time to the proof of self-evident results? Select the best answer. A: To gain mastery of, and confidence in, the methods of abstract proof to apply them in less obvious cases. (看这个看的想睡觉,可能是没有动手跟上老师的…
否定的逻辑 应该思考符号背后表示的逻辑,而不是像操作算术运算符一样操作逻辑符号. 比如 对于任意的 x,x属于自然数,那么 x 是偶数或者奇数:这是对的 如果使用“乘法分配律”拆分,变成“对于任意的x,x属于自然数,那么x是奇数或者对于任意的x,x属于自然数,那么x是奇数” 这是错的 疑惑 但是做练习的时候,还是把其当做符号来运算.For all 变成 at least one:At least one 变成 for all:v 变成 ^; 计算机也是把逻辑规则抽象成符号来运算的. 注意言论的…
there exists and all there exists 证明根号2是无理数 all 习题 3. Which of the following formal propositions says that there is no largest prime. (There may be more than one. You have to select all correct propositions.) The variables denote natural numbers. [6…
Deep Learning and Shallow Learning 由于 Deep Learning 现在如火如荼的势头,在各种领域逐渐占据 state-of-the-art 的地位,上个学期在一门课的 project 中见识过了 deep learning 的效果,最近在做一个东西的时候模型上遇到一点瓶颈于是终于决定也来了解一下这个魔幻的领域. 据说 Deep Learning 的 break through 大概可以从 Hinton 在 2006 年提出的用于训练 Deep Belief…
