- 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 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
- 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)
- 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

In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators B
- Equation of a rectangle - Mathematics Stack Exchange
I need to graph a rectangle on the Cartesian coordinate system Is there an equation for a rectangle? I can't find it anywhere
- geometry - What is the general equation for rotated ellipsoid . . .
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''
