test mathjax

$$
i\hbar\frac{\partial}{\partial t}\psi=-\frac{\hbar^2}{2m}\nabla^2\psi+V\psi
$$

inline mathjax $i\hbar\frac{\partial}{\partial t}\psi=-\frac{\hbar^2}{2m}\nabla^2\psi+V\psi$

test code

main.cpp

#include <iostream>
int main {
    std::cout << "hello world" << std::endl;
    std::cout << "hello world" << std::endl; std::cout << "hello world" << std::endl; std::cout << "helloworld" << std::endl; std::cout << "hello world" << std::endl;
    return 0;
}
