I want to write a fomula
\begin{equation}
fractional bandwidth = \frac{f_U-f_L}{f_C} \geq 0.25
\end{equation}
but it can't have any space between "fractional" and "bandwidth"
How can I do that? Thank you!
Use \text of package amsmath to format text in math equations.
\usepackage{amsmath}
...
\begin{equation}
\text{fractional bandwidth} = \frac{f_U-f_L}{f_C} \geq 0.25
\end{equation}
However, if these words were intended to be formatted like they are but with a space in between, you can insert spaces in math mode like this (a full list of spacing commands can be found here).
\begin{equation}
fractional \: bandwidth = \frac{f_U-f_L}{f_C} \geq 0.25
\end{equation}

By default math mode has the same color as the rest of the document text. I want it in such a way that the document text remains unaffected but anywhere math mode is used the color of the text within the math mode is whichever other preferred color.
All math environments? Add \AtBeginEnvironment{<environment name>} (defined in etoolbox) in your preamble. Example below demonstrates this with equation but you would need to add any other environment you use, as well
\documentclass{article}
\usepackage{mathtools}
\usepackage{xcolor}
\usepackage{etoolbox}
\AtBeginEnvironment{equation}{\color{red}}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{equation}
\label{eq:1}
x = y
\end{equation}
\lipsum[3][1]
\begin{equation}
\label{eq:2}
z = a + b
\end{equation}
\lipsum[2]
\end{document}
I have the following problem
\usepackage[fleqn]{amsmath}
\begin{equation}
\begin{split}
\min Y\\
\textrm{s.t.}
\end{split}
\end{equation}
\begin{align}
a+b=145641574\\
c+d<e
\end{align}
creates the following output:
So far so good. The formulas are essentially left-aligned. The numbering is right-aligned. But within the formulas, splits or line breaks result in right alignment. These should also be left-aligned.
Thanks in advance and have a nice weekend!
I'm using
\begin{equation}.. \end{equation} in markdown mode in a Colab notebook and I don't get equation numbering as I would expect from Latex.
Is there a fix for this?
One option would be to use \tag{}, e.g.
\begin{equation}
y = x \tag{1}
\end{equation}
or
\begin{align}
f(x) &= x \tag{1}, \\
g(x) &= x^2 + 2. \tag{2}
\end{align}
I am using latex for my report. I am stuck in centering a vector. This is my latex code:
\begin{equation}
\centering
X_{i}=
$$\begin{bmatrix}
C_1\\
C_2\\
C_3\\
\vdots\\
\vdots\\
\vdots\\
\vdots\\
C_n\\
OlValue\\
\end{bmatrix}$$
\label{Vect}
\end{equation}
The centering command doesn't work. I tried several things but the vector is not on the center.
You're doing it wrong...
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\noindent
X \dotfill X% To show the horizontal text width/margins
\begin{equation}
X_i =
\begin{bmatrix}
C_1 \\ C_2 \\
\vdots \\
C_n
\end{bmatrix}
\end{equation}
\end{document}
Don't use \centering inside an equation. Also don't use $$...$$. The equation environment automatically centres its contents, period.
When I use the following:
\begin{equation}
\overline{d} \overline{q}
\end{equation}
the overlines are misaligned, with the line on the q being lower than the line on the d. The same thing happens with \overrightarrow. Is there some way to fix this?
\vphantom could fix it:
\begin{equation}
\overline{d} \overline{q\vphantom{d}}
\end{equation}
\vphantom inserts vertical space according to the height of its argument and has zero width.
You can also use
\begin{equation}
\overline{\strut d} \overline{q \strut}
\end{equation}
