Bolded equations

Post by ghostanime2001 »

Why do the top equations look so much more darker and bolded than the bottom equations? The coding seems to be similar. Heeelp please.

Code: Select all

\documentclass[fleqn]{article}
\usepackage{fullpage}
\usepackage[left=1in,right=1in,top=1in,bottom=1in]{geometry}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{amsmath}
\usepackage[makeroom]{cancel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{xfrac}
\usepackage{siunitx}
\sisetup{%
  output-decimal-marker={.},
  load-configurations=abbreviations,
  group-separator={,},
  per-mode=fraction,
  fraction-function=\sfrac}
\usepackage{fix-cm}
\pagestyle{empty}
\begin{document}
\begin{enumerate}
\item
\raisebox{2ex}{\parbox[t]{2in}{\null\includegraphics[width=\linewidth]{Diagram1}}}
\hspace{1cm}
\begin{minipage}[t]{2in}
$\begin{aligned}[t]
r&=\text{3840 \cancel{mi}}\left(\dfrac{\text{1.609 \cancel{km}}}{\text{1 \cancel{mi}}}\right)\left(\dfrac{\text{1000 m}}{\text{1 \cancel{km}}}\right)=\SI{6.18e6}{\m} \\
s&=\frac{2\pi r\cos\theta}{T} \\
v&=\frac{2\pi(\SI{6.37e6}{\m})\cos\SI{40.1}{\degree}}{\SI{1}{\hour}} \\
v&=\SI{354.34}{\m\per\s}
\end{aligned}$
\end{minipage}
\item
\raisebox{2ex}{\parbox[t]{2in}{\null\includegraphics[width=\linewidth]{Diagram2}}}
\begin{minipage}[t]{2in}
$\begin{aligned}[t]
d&=\SI{328}{\m} \\
r&=\SI{6.18e6}{\m} \\
T&=\dfrac{(\SI{6.37e6}{\m})\cos\SI{40.1}{\degree}}{\SI{86400}{\s}} \\
T&=\dfrac{2\pi(\SI{6.37e6}{\m})\cos\SI{40.1}{\degree}}{\SI{1}{\s}} \\
v&=\SI{354.34}{\m\per\s}
\end{aligned}$
\end{minipage}
\item
\raisebox{2ex}{\parbox[t]{2in}{\null\includegraphics[width=\linewidth]{Diagram3}}}
\begin{minipage}[t]{2in}
$\begin{aligned}[t]
d&=\SI{328}{\m} \\
r&=\SI{6.18e6}{\m} \\
T&=\dfrac{(\SI{6.37e6}{\m})\cos\SI{40.1}{\degree}}{\SI{86400}{\s}} \\
T&=\dfrac{2\pi(\SI{6.37e6}{\m})\cos\SI{40.1}{\degree}}{\SI{1}{\s}} \\
v&=\SI{354.34}{\m\per\s}
\end{aligned}$
\end{minipage}
\end{enumerate}
\end{document}

The numbers look the same, in the first equation you use bigger and thus thicker parentheses, and you use \text font. Also here you should use \SI units. Cancelling makes the optical impression even stronger.
