If you want to write Tex math expressions on the same line you can use:
$a^2 + b^2 = c^2$
Eg:
Expressions like $a^2 + b^2 = c^2$ on the same line
Expressions like $a^2 + b^2 = c^2$ on the same line
\(1+2+\dots+n=\frac{n(n+1)}{2}\)
Eg:
Or expressions like \(1+2+\dots+n=\frac{n(n+1)}{2}\)
Or expressions like \(1+2+\dots+n=\frac{n(n+1)}{2}\)
If you want to write TeX math expressions on its own line use:
$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$
Eg:
Expressions like $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$
Expressions like $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$
\[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]
Eg:
Or like \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]
Or like \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]
Also, you can use a wide range of TeX math enviroments like: align, align*, alignat, alignat*, displaymath, eqnarray, eqnarray*, equation, equation*, flalign, flalign*, gather, gather*, math, multline, multline*
Eg:
\begin{align*}
e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\
& = \sum_{n\geq 0} \frac{x^n}{n!}
\end{align*}
\begin{align*}
e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots
& = \sum_{n\geq 0} \frac{x^n}{n!}
\end{align*}
Note: math environments should not be inside the dollar sign delimiters; the environments should stand on their own with just the \begin and \end statements in order to be parsed correctly.
