This is a paragraph that I am including in my printout to demonstrate the inclusion
of equations in the body of a laboratory report. The stand-alone version of an equation
appears as follows,
𝑒
−𝑒
1
𝑏 +𝑝
𝑑𝑥 = ln
𝑥 sec(𝑝𝑥)
2
𝑎 +𝑝
,
where a, b, p, and c are constants. The comma next to the equation is included because it
is common practice to treat equations as if they were words in a sentence. For
comparison, the same equation presented inline to the text appears as
∫
(
)
𝑑𝑥 = ln
better fit in a line of text.
. The inline format compresses the equation vertically to
(𝐶. 3)
