- 在理工科中，Formula, Equation 和 Function 这三个词有什么异同？
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
- What is the difference between equation and formula?
An equation is any expression with an equals sign, so your example is by definition an equation Equations appear frequently in mathematics because mathematicians love to use equal signs A formula is a set of instructions for creating a desired result Non-mathematical examples include such things as chemical formulas (two H and one O make H2O), or the formula for Coca-Cola (which is just a
- 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 vs nonlinear differential equation - Mathematics Stack Exchange
How to distinguish linear differential equations from nonlinear ones? I know, that e g : $$ y''-2y = \\ln(x) $$ is linear, but $$ 3+ yy'= x - y $$ is nonlinear Why?
- analysis - How to tell if a differential equation is homogeneous, or . . .
Sometimes it arrives to me that I try to solve a linear differential equation for a long time and in the end it turn out that it is not homogeneous in the first place Is there a way to see direc
- What is the equation for a 3D line? - Mathematics Stack Exchange
I love your answer for a line equation in the form of z = f (x, y) Unfortunately calculating square roots can be impractical from the calculational standpoint and hence I really doubt any plotting software will be able to graph it correctly
- The equation of a line reflected about another line
The equation for your reflected line can be constructed using the point-slope form, $y=m (x-x_Q)+y_Q$ The point $ (x_Q,y_Q)$ is easily obtained as the intersection of your "mirror" line (the blue one) and the line to be reflected (the solid red one)
- 中文中“方程”（英文Equation）一词是如何来的？ - 知乎
中文中“方程”（英文Equation）一词是如何来的？ 英语中 Equal 是相等的意思，用 Equation 表示方程很自然，很容易理解，因为方程的本质就是一个等式，只是含有未知数。 为何在中文中没有使用”… 显示全部 关注者 12 被浏览
