Insert Equation

You can insert equations into a flashcard using the TeX language. Additional symbols here and here.

Basics: Symbols are a slash followed by a symbol name. Anything between 2 curly braces represents a logical group.

Try typing in one of the example equations:



Equation Examples
Result
x + y - a \times b \cdot c

2^n \times 2_x

\frac{x+t}{y}
\sum_{k=1}^n k = \frac{n(n+1)}{2}
\max_{0\le x\le 1}x(1-x)=1/4
\lim_{x\to\infty}f(x)=0

x = \frac{-b \pm \sqrt {b^2-4ac}}{2a}
