Some sample math

Here is some sample math added to this page as an inline directive \(a^2 + b^2 = c^2\).

Here is some math added to this page:

\[ \begin{align}\begin{aligned}(a + b)^2 = a^2 + 2ab + b^2\\(a - b)^2 = a^2 - 2ab + b^2\end{aligned}\end{align} \]

And another…

\[\begin{split}(a + b)^2 &= (a + b)(a + b) \\ &= a^2 + 2ab + b^2\end{split}\]

And another…

\begin{eqnarray} y & = & ax^2 + bx + c \\ f(x) & = & x^2 + 2xy + y^2 \end{eqnarray}

And some more…

(1)\[e^{i\pi} + 1 = 0\]

Euler’s identity, equation (1), was elected one of the most beautiful mathematical formulas.
