A\subseteq B\: \wedge\:B\subseteq A\:\Rightarrow\:A=B

Many many people used LaTeX many many years ago. At the beginning, typing with LaTeX is quite difficult, I’m used to use Equation Editor in WORD. However, it is a very beginning (too old to start), I think it is worthy trying here.

V_{y=k}=\pi\displaystyle \int_a^b(f(x)-k)^2dx

V_{x=k}=\pi\displaystyle \int_a^b(f(y)-k)^2dy

  2. Quite good!

    3^3 + 4^3 + 5^3 = 6^3

  3. \lim_{x\rightarrow 0} \frac{\sin x}{x} = 1

    Why? The x\rightarrow 0 is not under \lim directly?

  4. \left(\begin{array}{rcl}\alpha&\beta&\gamma\\\delta&\epsilon&\zeta\\\eta&\theta&\iota\\\end{array}\right)
    Oh! Don’t use “enter" to make the ‘good-looking’ presentation, we need ‘ONE-LINE’ to type Latex.

  7. Compare \int_0^1f(x)dx with \int_0^1 f(x)dx

    \frac{\pi}{4} = 1 - \frac{1}{3} + \frac{1}{5} - \frac{1}{7} + \frac{1}{9} - \dots

  9. Comment #7

    Add the following just in front of the second dollar sign

    &bg=ffffff&fg=000000&s=1

    Comment #8

    Only

    &bg=ffffff&fg=000000

    So, to make darker formula, use size = 1, i.e. in comment #7
