- 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
- linear algebra - Equation of a plane passing through 3 points . . .
In fact, it’s possible to do better and write down an equation of the plane directly Every other point (x, y, z) (x, y, z) on the plane also generates a linear equation in the coefficients of the plane equation
- What exactly is an equation? - Mathematics Stack Exchange
An equation is simply a statement that two things are equal To be more specific than that, you'd probably have to specify the domain under discussion
- 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)
- 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
- Compute the characteristic equation of a $3 \\times 3$ matrix
The characteristic equation is used to find the eigenvalues of a square matrix A First: Know that an eigenvector of some square matrix A is a non-zero vector x such that Ax = λx
- 在理工科中，Formula, Equation 和 Function 这三个词有什么异同？ - 知乎
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 发布于 2015-01-01 01:46 知乎用户 formula： （1）化学式，分子式；
