derivatives, Limits, sums and integrals
The expressions are obtained in LaTeX by typing \frac{du}{dt} and \frac{d^2 u}{dx^2. The mathematical symbol is produced using \partial. Thus the Heat equation is obtained in LaTeX by typing
\[\frac{\partial u}{\partial T}
= h^2 \left (\frac{\partial^2 u}{\partial x^2}
+ \frac{\partial^2 u}{\partial y^ 2}
+ \frac{\partial^2 u}{\partial z^2} \right) \]

strong and weak types? Which one is better? Why?What is strong-typing versus weak-typing? Which is preferred? Why?

For details about the progress, refer to this issue. Some other Python tools (such as the code
they are full, but many people do not want to admit it. The major benefit of the weak type lies in the convenience brought by the implementation of some other language features. Such as closures and callback functions. I don't understand PHP, But javascript relies heavily on callback functions and the derived error first callback pattern, which cannot be implemented in strong languages. Of course, there are other non-weak type implementations. for example, Ruby will use argument as hash to avoi
