# Power series, Taylor series and Functions

Since recently I am dealing with numerical solution of differential equation, I recalled that not long time ago I’ve actually learned about $e^x$ and Euler’s equation. They should be close related to the differential equation topic. So let’s review some of the conclusions I learned from the book: “オイラーの公式がわかる”.

# Javascript scope and closure

Today let me try to explain some of the strange behavior of Javascript (compared to Python).

# Odinary Differential Equations (ODE)

In this post I want present some of the basic of Odinary Differential Equations, as a preparation for future post discussing solution method and numerical method for the ODE.

# Python module import

Let’s recap some of the most common syntaxs in Python (related to modules and classes).

# Git learning note

Finally I am released from a long-term report mission so …
