[edit] Language
"An unitary" or "an union" or "an university" were used in the 18th century, but now "a" rather than "an" is standard when the initial sound is "yoo".
[edit] Naming convention
[edit] HTML math
[edit] Minus sign
Use [−1,1] instead of [-1,1]. The little hyphen is too short to be a minus sign.
[edit] TeX
[edit] Colon
instead of
[edit] Mapping arrows
When you want to define the domain and codomain of the mapping use
but when you define the actual mapping function use
[edit] Standard function names
Use
- eix = cosx + isinx
instead of
- eix = cosx + isinx
to prevent the function names from looking like a variable.
[edit] Imaginary unit
The imaginary unit i should not be confused with the common variable i. So to make the imaginary unit look different it is better to write
- eix = cosx + isinx
than
- eix = cosx + isinx
[edit] Embedded fractions
When a fraction is in a superscript or otherwise deeply embedded within some other notation, it is often more legible like this
than like this
[edit] Spacing
[edit] Integrals
Use
rather than
[edit] Sets defined by using braces
This is another place where small spacing adjustments make notation look better. This
is better than this
- {f(x):0 < x < 2}
