- What is the difference between equation and formula?
An equation is meant to be solved, that is, there are some unknowns A formula is meant to be evaluated, that is, you replace all variables in it with values and get the value of the formula Your example is a formula for mpg But it can become an equation if mpg and one of the other value is given and the remaining value is sought
- latex中equation环境相比align环境有何优势? - 知乎
首先，我们要明白这两个环境分别能干什么。下面两段文字摘抄自l-short: 单独成行的行间公式在LaTeX里由equation环境包裹。 更多情况的是，我们需要罗列一系列公式，并令其按照等号对齐。目前最常用的是align环境，它将公式用 分隔为两部分并对齐。 通俗地讲，equation环境是处理行间公式的一种
- What exactly is an equation? - Mathematics Stack Exchange
One approach: An equation is a predicate, P(x) P (x), of the form s(x) = t(x) s (x) = t (x) where x x is a free variable (or vector of free variables) and s(x), t(x) s (x), t (x) are terms -- expressions which evaluate to elements of the universe (e g real numbers if you are doing mathematics over the reals) when values are substituted for variables This means that P(x) P (x) is something
- 在理工科中，Formula, Equation 和 Function 这三个词有什么异同？ - 知乎
equation：等式，方程式 英英释义： An assertion that two expressions are equal, expressed by writing the two expressions separated by an equal sign; from which one is to determine a particular quantity
- simple geometry question- equation of cylinder
All points on it have x=0 and y=0 Clearly it is a line with any z-allowed You could write the equation of the axis as x2 +y2 = 0 x 2 + y 2 = 0, because in the reals the only solution to this equation is x = 0 x = 0 and y = 0 y = 0 This shows you that the z-axis is like an infinitely thin cylinder (with a point cross section 0 radius)
