- What is the difference between equation and formula?
An equation is a statement that connects two expressions with an $=$ sign and asserts their equality An identity is an equation that holds for every variable tuple for which the equation is defined: $\log(xy)\equiv \log(x)+\log(y)$ A conditional equation holds for some variable tuple(s):
- latex中equation环境相比align环境有何优势? - 知乎
与equation环境相似的，可以用equation*环境生成不带编号的行间公式。与之相似的还有最常用的无编号行间公式环境 \[ \]，以及现在基本被淘汰的 $$ $$ 环境。当然，还有完全等价的displaymath环境。下面是这三种环境的简单示例：

- simple geometry question- equation of cylinder
The equation of an object is a way of telling whether a point is part of an object -- if you substitute the coordinates of the point into the equation and the equation is true, then the point is on the object; if the equation is not true for that point, then the point is not on the object
- 在理工科中，Formula, Equation 和 Function 这三个词有什么异同？ - 知乎
Equation常指方程,用方程来求解未知数,或者解出多个未知数间的对应关系 equation作为等式用的情况我感觉不常见,可能是某些常用的方便计算的式子,或者某些先决条件 inquation也就是不等式用的还要多些 Function是函数,一种普遍的对应关系,通常还要满足单射

$\begingroup$ The equation has the form of a generic second degree equation in three unknowns but, in general, it os mot so simple to see what kind of quadric surface this equation represents If you are interested on this topic you can search for ''quadratic forms''
