Since it is just a sort of discussion, I will just give the formula and condition without proving them or leaving examples. General: Line integral(Work and in the plane) $\int_{C}\vec{F}\cdot \mathrm{d}\vec{r} = \int_{C}M\mathrm{d}x+N\mathrm{d}y$, in…

Well, to begin with, I'd like to say thank you to MIT open courses twice. It's their generosity that gives me the priviledge to enjoy the most outstanding education resources. Okay, come to the point -- The Frequency in Oscillation System. In general…

At first, I'd like to say thank you to MIT open courses which give me the privilege to enjoy the most outstanding education resources. Okay, come to the point. When I was learning the second-order homogeneous differential equation, the professor quot…

前言 MATLAB一向是理工科学生的必备神器,但随着中美贸易冲突的一再升级,禁售与禁用的阴云也持续笼罩在高等学院的头顶.也许我们都应当考虑更多的途径,来辅助我们的学习和研究工作. 虽然PYTHON和众多模块也属于美国技术的范围,但开源软件的自由度毕竟不是商业软件可比拟的. 本文是一篇入门性文章,以麻省理工学院(MIT) 18.06版本线性代数课程为例,按照学习顺序介绍PYTHON在代数运算中的基本应用. 介绍PYTHON代数计算的文章非常多,但通常都是按照模块作为划分顺序,在实际应用中仍然有较多…
