1.3 The Game of the Name
(전략)
One of the hardest things about using $\LaTeX$ is deciding how to pronounce it. This is also one of the few things I'm not going to tell you about $\LaTeX$, since pronunciation is best determined by usage, not flat. $\TeX$ is usually pronounced teck, making lah-teck, and lay-teck the logical choices; but language is not always logical, so lay-tecks is also possible.

$$\sum_{n=1}^\infty a_n = \int_0^1 f$$
$$SSIM(x, y) = \frac{(2\mu_x\mu_y + C_1)(2\sigma_{xy} + C_2)}{(\mu_x^2 + \mu_y^2 + C_1)(\sigma_x^2 + \sigma_y^2 + C_2)}$$
$$\Delta E = \sqrt{(\Delta L^*)^2 + (\Delta a^*)^2 + (\Delta b^*)^2}$$
