- 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
- 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
- Understanding the Equation of a Möbius Strip
Is there a reason you need an equation for the Mobius band? In terms of topology, there are much much easier ways of defining the Mobius band, in terms of gluing ends of a strip together

- algebra precalculus - How to derive the polar equation of a circle . . .
I have learnt that the standard equation of a circle whose centre is at (a,b) is $$(x-a)^2 + (y-b)^2 = c^2 $$ I am trying to derive the polar equation of this circle but I am unfortunately stuck $$\\
- surfaces - How to derive the 3D equation of a torus? - Mathematics . . .
0 First of all, to understand how the equation for a torus relates to that of a circle you must become familiar with the object: x2 +y2− −−−−−√ x 2 + y 2 As you can probably guess, this takes any point p p on the x x - y y plane and generates p p 's distance from the origin
- 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
- 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
