- 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):

- terminology - What does it mean to solve an equation? - Mathematics . . .
In most cases an equation represents a problem (or question) of some kind, and when we say that we are "solving" the equation what we really mean is that we are solving the problem (or answering the question) In other words, the meaning of "solving an equation" is determined only by the context

- Equation of a rectangle - Mathematics Stack Exchange
If the equations of the diagonals of the rectangle are Ax + By + C = 0 and Dx + Ey + F = 0 then an equation for the rectangle is: M|Ax + By + C| + N|Dx + Ey + F| = 1 M and N can be found by substituting the coordinates of two adjacent vertices of the rectangle In fact, this equation can be used to describe any parallelogram

- 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
