Alphabet A,
A* = {alll strings consisting symbols from A}
A subset L of A* is called a language
Question: For a language L, does exist an algorithm to check for any x, if x is in L?

This’s the note of CPT205 W2.

The topics for this week:

1. Computer representation of objects
2. Cartesian co-ordinate system
3. Points, lines and angles
4. Trigonometry 三角函数
5. Vectors (unit vector) and vector calculations (addition, subtraction, scaling, dot product, cross product) 矢量和矢量计算
6. Matrices (dimension, transpose, square/symmetric/identity, inverse) and matrix calculations (addition, subtraction, multiplication) 矩阵和矩阵计算

因为矩阵的知识快忘光了，所以矩阵的部分写的比较多。

This note is about the Lecture 2 of CPT203.

This week we will focus on three following spots.

• understand the concepts of software processes and software process models;
• introduced to three generic software process models and when they might be used;
• know about the fundamental process activities of software requirements engineering, software development, testing, and evolution;

Decision, Computation and Language
This module is about the theory of computation and answering the question: “What are the fundamental capabilities and limitations of computers?”
这个模块是关于计算理论的，并回答这个问题:“计算机的基本能力和局限性是什么?”
The central theme: Are the languagues, their membership problems can not be solved (computed) Algorithmically.
