$\mbox{ is it?}$ so it is

4. $\int_0^{2\pi}\left( \frac{sin(\alpha)\cdot(x + cos(\alpha)r)} {(x^2 + r^2 + 2cos(\alpha)xr)^{1.5}}\right)\partial \alpha\ \equiv\ \frac{2}{x^2}$

5. $tan \theta = \frac{a_1 - c_1}{b_1 - m_1}$
$\lim_{x \to {\frac{3}{2}}^+}$
[tex]\cot^2t[\math]

6. test

$v\left({t}\right)=e^{-\hat{\varphi}\left({t}\right)}\cos{\left(2\pi f_{c}{t}+\varphi\left({t}\right)\right)}$

7. $h(x) = \frac{\log_{10}x}{x}$

8. $2+2=5$

9. test

$x^2$

10. ## Test

$\boxplus \quad \boxminus \quad \boxdot$

$\Re \quad \Im$

$\curvearrowright \quad \curvearrowleft$

$\leftrightarrows \quad \rightleftarrows$

$\leftleftarrows \quad \rightrightarrows \quad \upuparrows \quad \downdownarrows$

11. How does one make a double countor integral in LaTeX?
It came up in a post but I had no idea.

You know,
$\oint$
Is a single countor integral.

A double is,
$\int \int$
But there is a bigger circle passing through both of these.

12. Hello, ThePerfectHacker!

Some systems use \oiint and \varoint
. . but they don't work here . . . sorry.

Ha! I found one thing LaTeX cannot do.
But you have to agree the double contour integral is the coolest looking math symbol.

If you were really "ThePerfectHacker", you could edit latex to include that variable and image! Shame!

You misunderstand the meaning of "Hacker." He's a taxi driver.
