Syntax for parts of Latex that I tend to use the most.

Inline Equations

To specify an equation inline (i.e. in the same line as your text), simply surround the equation with $$.

Code:

My equation is $$ y = 8x $$ and I'm proud of it!

Output:

My equation is \(y = 8x\) and I’m proud of it!

Next Line Equation

To specify an equation in the next line (in the center of the line), add a \ in front of the first $$, i.e. \$$:

Code:

This equation will appear in the next line, in the center: \$$ y = 3x $$.

Output:

This equation will appear in the next line, in the center: $$ y = 3x $$

Subscript

Code:

x_1

Output: \(x_1\)

Multi-letter subscript, Code:

x_{1d}

Output: \(x_{1d}\)

Fraction

Code:

\frac{topExpression}{bottomExpression}

Output: \(\frac{topExpression}{bottomExpression}\)

Vector

Code:

\vec{a}

Output: \(\vec{a}\)

Sum

Code

\sum_{n}

Output: \(\sum_{n}\)

Sum With Top Bound

Code

\sum_{n=1}^3

Output: \(\sum_{n=1}^3\)

Dot product

Code (\cdot)

\vec{a} \cdot \vec{b}

Output: \(\vec{a} \cdot \vec{b}\)
