Blot will convert equations set in LaTeX. Wrap your LaTeX in two dollar signs () like this: $$f(x) = 2x^2 + 2/3$$  ### Accents  $a’$ a’ $\ddot{a}$ \ddot{a} $\overleftarrow{AB}$ \overleftarrow{AB} $\overrightarrow{AB}$ \overrightarrow{AB} $a’’$ a’′ $\grave{a}$ \grave{a} $\underleftarrow{AB}$ \underleftarrow{AB} $\underrightarrow{AB}$ \underrightarrow{AB} $a^{\prime}$ a^{\prime} $\hat{\theta}$ \hat{\theta} $\overleftrightarrow{AB}$ \overleftrightarrow{AB} $\overbrace{AB}$ \overbrace{AB} $\acute{a}$ \acute{a} $\widehat{ac}$ \widehat{ac} $\underleftrightarrow{AB}$ \underleftrightarrow{AB} $\underbrace{AB}$ \underbrace{AB} $\bar{y}$ \bar{y} $\tilde{a}$ \tilde{a} $\overgroup{AB}$ \overgroup{AB} $\overlinesegment{AB}$ \overlinesegment{AB} $\breve{a}$ \breve{a} $\widetilde{ac}$ \widetilde{ac} $\undergroup{AB}$ \undergroup{AB} $\underlinesegment{AB}$ \underlinesegment{AB} $\check{a}$ \check{a} $\vec{F}$ \vec{F} $\overleftharpoon{ac}$ \overleftharpoon{ac} $\overrightharpoon{ac}$ \overrightharpoon{ac} $\dot{a}$ \dot{a} $\overline{AB}$ \overline{AB} $\Overrightarrow{AB}$ \Overrightarrow{AB} $\utilde{AB}$ \utilde{AB} $\underline{AB}$ \underline{AB} See also letters. #### Accent functions inside \text{…}  $\text{'{a}}$ '{a} $\text{\~{a}}$ \~{a} $\text{\.{a}}$ \.{a} $\text{\H{a}}$ \H{a} $\text{\{a}}$ \{a} $\text{\={a}}$ \={a} $\text{"{a}}$ "{a} $\text{\v{a}}$ \v{a} $\text{\^{a}}$ \^{a} $\text{\u{a}}$ \u{a} $\text{\r{a}}$ \r{a} ### Delimiters  $(\,)$ ( ) $\lgroup\:\rgroup$ \lgroup\rgroup $\lceil\:\rceil$ \lceil\rceil $\uparrow$ \uparrow $[\:]$ [ ] $\lbrack\:\rbrack$ \lbrack\rbrack \lﬂoor\:\rﬂoor \lﬂoor\rﬂoor $\downarrow$ \downarrow $\{\,\}$ \{ \} $\lbrace\:\rbrace$ \lbrace\rbrace $\ulcorner \urcorner$ \ulcorner\urcorner $\updownarrow$ \updownarrow $\langle\:\rangle$ \langle\rangle $\lt\:\gt$ \lt\gt $\llcorner \lrcorner$ \llcorner\lrcorner $\Uparrow$ \Uparrow $|$ | $\vert$ \vert $\backslash$ \backslash $\Downarrow$ \Downarrow $\|$ \| $\Vert$ \Vert $\lmoustache\:\rmoustache$ \lmoustache\rmoustache $\Updownarrow$ \Updownarrow $\lvert\;\rvert$ \lvert\rvert $\lVert\;\rVert$ \lVert\rVert \left. \right. #### Delimiter Sizing  $\left(\LARGE{AB}\right)$ \left( \LARGE{AB} \right) \left \big \bigl \bigr \middle \Big \Bigl \Bigr $( \big( \Big( \bigg( \Bigg($ ( \big( \Big( \bigg( \Bigg( \right \bigg \biggl \biggr \Bigg \Biggl \Biggr ### Environments  $$\begin{matrix} a & b \\ c & d \end{matrix}$$ \begin{matrix} a & b \\ c & d \end{matrix} $$\begin{array}{c|c} a & b \\ c & d \end{array}$$ \begin{array}{c|c} a & b \\ c & d \end{array} \begin{aligned} a&=b+c \\ d+e&=f \end{aligned} \begin{aligned} a&=b+c \\ d+e&=f \end{aligned} $$\begin{pmatrix} a & b \\ c & d \end{pmatrix}$$ \begin{pmatrix} a & b \\ c & d \end{pmatrix} $$\begin{bmatrix} a & b \\ c & d \end{bmatrix}$$ \begin{bmatrix} a & b \\ c & d \end{bmatrix} \begin{alignedat}{2}10&x+&3&y=2\\3&x+&13&y=4\end{alignedat} \begin{alignedat}{2} 10&x+ &3&y = 2 \\ 3&x+&13&y = 4 \end{alignedat} $$\begin{vmatrix} a & b \\ c & d \end{vmatrix}$$ \begin{vmatrix} a & b \\ c & d \end{vmatrix} $$\begin{Vmatrix} a & b \\ c & d \end{Vmatrix}$$ \begin{Vmatrix} a & b \\ c & d \end{Vmatrix} $$\begin{gathered} a=b \\ e=b+c \end{gathered}$$ \begin{gathered} a=b \\ e=b+c \end{gathered} $$\begin{Bmatrix} a & b \\ c & d \end{Bmatrix}$$ \begin{Bmatrix} a & b \\ c & d \end{Bmatrix} $$x = \begin{cases} a &\text{if } b \\ c &\text{if } d \end{cases}$$ x = \begin{cases} a &\text{if } b \\ c &\text{if } d \end{cases} There is also support for {darray} and {dcases}. Acceptable line separators include: \\, \cr, and \\[distance]. Distance can be written with any of the units. The {array} environment does not yet support \hline. ### Letters  Γ \Gamma Δ \Delta Θ \Theta Λ \Lambda Ξ \Xi Π \Pi Σ \Sigma Υ \Upsilon Φ \Phi Ψ \Psi Ω \Omega α \alpha β \beta γ \gamma δ \delta ϵ \epsilon ζ \zeta η \eta θ \theta ι \iota κ \kappa λ \lambda μ \mu ν \nu ξ \xi o \omicron π \pi ρ \rho σ \sigma τ \tau υ \upsilon ϕ \phi χ \chi ψ \psi ω \omega ε \varepsilon ϰ \varkappa ϑ \vartheta ϖ \varpi ϱ \varrho ς \varsigma φ \varphi ϝ \digamma Direct Input: Γ Δ Θ Λ Ξ Π Σ Υ Φ Ψ Ωα β γ δ ϵ ζ η θ ι κ λ μ ν ξ o π ρ σ τ υ ϕ χ ψ ω ε ϑ ϖ ϱ ς φ #### Other Letters  $\imath$ \imath $\jmath$ \jmath ℵ \aleph ℶ \beth ℷ \gimel ℸ \daleth ð \eth Ⅎ \Finv ⅁ \Game ℓ \ell ℏ \hbar ℏ \hslash ℑ \Im ℜ \Re ℘ \wp ∂ \partial ∇ \nabla $\Bbbk$ \Bbbk  Direct Input: ℂ ℍ ℕ ℙ ℚ ℝ ℤ ∂ ð ∇ ℑ ℓ ℘ ℜ Ⅎ ℵ ℶ ℷ ℸ ⅁ ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝÞàáâãäåçèéêëìíîïðñòóôöùúûüýþÿ #### Letters inside \text{} \text{…} will accept the functions: \ae, \AE, \oe, \OE, \o, \O, \ss, \i, \j. \text{…} also accepts Unicode characters from: ScriptUnicode RangeScriptUnicode Range Latin-10080 — 00FFSinhala0D80 — 0DFF Cyrillic0400 — 04FFThai0E00 — 0E7F Devanagari0900 — 097FLao0E80 — 0EFF Bengali0980 — 09FFTibetan0F00 — 0FFF Gurmukhi0A00 — 0A7FCJK symbols and punctuation3000 — 303F Gujarati0A80 — 0AFFHiragana3040 — 309F Oriya0B00 — 0B7FKatakana30A0 — 30FF Tamil0B80 — 0BFFCJK ideograms4E00 — 9FAF Telugu0C00 — 0C7FHangulAC00 — D7AF Kannada0C80 — 0CFFFull width punctuationFF00 — FF60 Malayalam0D00 — 0D7F ### Annotation  $\cancel{5}$ \cancel{5} $\overbrace{a+b+c}^{\text{note}}$ \overbrace{a+b+c}^{\text{note}} $\bcancel{5}$ \bcancel{5} $\underbrace{a+b+c}_{\text{note}}$ \underbrace{a+b+c}_{\text{note}} $\xcancel{ABC}$ \xcancel{ABC} $\boxed{\pi = \frac c d}$ \boxed{\pi=\frac c d} $\sout{abc}$ \sout{abc} $\not =$ \not = ### Overlap  ${=}\mathllap{/\,}$ {=}\mathllap{/\,} $\left(x^{\smash{2}}\right)$ \left(x^{\smash{2}}\right) $\mathrlap{\,/}{=}$ \mathrlap{\,/}{=} $\sqrt{\smash[b]{y}}$ \sqrt{\smash[b]{y}} $\displaystyle \sum_{\mathclap{1\le i\le j\le n}} x_{ij}$ \sum_{\mathclap{1\le i\le j\le n}} x_{ij} There is also support for \llap, \rlap, and \clap, but they will take only text, not math, as arguments. ### Spacing FunctionProducesFunctionProduces \!³∕₁₈ em space\kern{distance}space, width = distance \,³∕₁₈ em space\mkern{distance}space, width = distance \thinspace³∕₁₈ em space\skip{distance}space, width = distance \:⁴∕₁₈ em space\mskip{distance}space, width = distance \medspace⁴∕₁₈ em space\hspace{distance}space, width = distance \;⁵∕₁₈ em space\hspace*{distance}space, width = distance \thickspace⁵∕₁₈ em space\phantom{content}space the width and height of content \enspace½ em space\hphantom{content}space the width of content \quad1 em space\vphantom{content}a strut the height of content \qquad2 em space ~non-breaking space \spacenon-breaking space \spacenon-breaking space  Notes: {distance} will accept any of the units.\mkern and \mskip will not work in text mode and both will write a console warning for any unit except mu.

behaves like a switch.  $\color{blue} F=ma$ \color{blue} F=ma $\color{#fc625d} F=ma$ \color{#fc625d} F=ma Other color functions always expect the content to be a function argument.  $\textcolor{forestgreen}{F=ma}$ \textcolor{forestgreen}{F=ma} $\textcolor{#fc625d}{F=ma}$ \textcolor{#fc625d}{F=ma} $\colorbox{gold}{A}$ \colorbox{gold}{A} $\fcolorbox{black}{gold}{A}$ \fcolorbox{black}{gold}{A} For color deﬁnition, color functions will accept the standard HTML predeﬁned color names. They will also accept an RGB argument in CSS hexa­decimal style. ### Font  AB \mathrm{AB} AB \mathbf{AB} AB \mathit{AB} AB \mathsf{AB} AB \mathtt{AB} AB \textrm{AB} AB \textbf{AB} AB \textit{AB} AB \textsf{AB} AB \texttt{AB} AB \rm{AB} AB \bf{AB} AB \it{AB} AB \sf{AB} AB \tt{AB} AB \textnormal{AB} AB \bold{AB} AB \Bbb{AB} AB \mathcal{AB} AB \frak{AB} AB \text{AB} AB \boldsymbol{AB} AB \mathbb{AB} AB \mathscr{AB} AB \mathfrak{AB} AB \bm{AB} One can stack font family, font weight, and font shape by using the \textXX versions of the font functions. So \textsf{\textbf{H}} will produce $\textsf{\textbf{H}}$. The other versions so not stack, e.g., \mathsf{\mathbf{H}} will produce $\mathsf{\mathbf{H}}$. #### Size  $$\Huge AB$$ \Huge AB $$\normalsize AB$$ \normalsize AB $$\huge AB$$ \huge AB $$\small AB$$ \small AB $$\LARGE AB$$ \LARGE AB $$\footnotesize AB$$ \footnotesize AB $$\Large AB$$ \Large AB $$\scriptsize AB$$ \scriptsize AB $$\large AB$$ \large AB $$\tiny AB$$ \tiny AB #### Style  $\displaystyle\sum_{i=1}^n$ \displaystyle\sum_{i=1}^n $\textstyle\sum_{i=1}^n$ \textstyle\sum_{i=1}^n $\scriptstyle x$ \scriptstyle x The size of a ﬁrst sub/superscript $\scriptscriptstyle x$ \scriptscriptstyle x The size of subsequent sub/superscripts $\lim\limits_x$ \lim\limits_x $\lim\nolimits_x$ \lim\nolimits_x $\verb! x^2 !$ \verb!x^2! $\text{x}$ \text{x} \text{…} will accept nested …$ fragments and render them in math mode. \text{…} will render an extended range of characters.

### Units

Units are proportioned as they are in TeX instead of CSS.

UnitValueUnitValue
emCSS embp$\frac 1{72}$ inch × F × G
exCSS expc12 $\TeX$pt
mu$\frac 1{18}$ CSS emdd$\frac{1238}{1157}$ $\TeX$pt
pt$\frac 1{72.27}$ inch × F × G   cc$\frac{14856}{1157}$ $\TeX$pt
mm1 mm × F × Gnd$\frac{685}{642}$ $\TeX$pt
cm1 cm × F × Gnc$\frac{1370}{107}$ $\TeX$pt
in1 inch × F × Gsp$\frac 1{65536}$ $\TeX$pt
 where: F = $$\large \frac{\text{font size of surrounding HTML text}}{10\text{ pt}}$$ G = 1.21 by default, because $\TeX$ font-size is normally 1.21 × the surrounding font size. This value can be over-ridden by the CSS of an HTML page. For example, on this page, G = 1.0.
