ghost中实现数学公式方法

最简单的办法，在撰写文章时直接插入 MathJax的html代码。代码示例： <script src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script> 行内公式：\( a^2 + b^2 = c^2 \) 效果展示 \( a^2 + b^2 = c^2 \) \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \) \( e^{i\pi}

Energy Transfer

Energy Transfer

1. Forms of Energy • Kinetic Energy (KE): Energy stored due to the motion of the object Where m is mass and v is velocity. • Potential Energy (PE): Energy stored due to position in a force field. • Gravitational Potential Energy (GPE):Energy stored due to position in a gravitational force field.

Type of Forces

Types of Forces in AS-Level Physics At AS level, forces are categorized into different types based on how they act and their effects on objects. Here’s a closer look at key force types, including weight, normal contact force, frictional force, resistive force, and upthrust. Force is the rate of

Type and Property of Wave

1.How to describe a wave * Wavelength λ unit:meter m Definition:Distance between two adjacent wavefronts OR Distance between two adjacent points which are oscillating in phase * Frequency f unit:Hertz Hz Definition:Number of oscillation completed per unit time * Wave speed v unit:meter/second m/s * Period

Integration

积分是微积分中的重要部分，它是微分的逆运算。在A-level数学中，积分主要分为不定积分（Indefinite Integration）和定积分（Definite Integration） 1. 不定积分不定积分给出函数的原函数形式，并包含一个常数项 C（积分常数）。基本积分公式 1. 幂函数积分： 2. 指数函数积分： 3. 三角函数积分： 4. 复合函数积分（代换法的基础）： 2. 定积分定积分用于计算曲线下的面积，其结果为一个具体值，没有积分常数 C。其中，F(x) 是 f(x) 的一个原函数几何意义 • 定积分表示曲线 y = f(x) 与 x-轴之间从 x = a 到 x = b
