$$\int_{0}^{\frac{\pi}{2}} \log \cos \kappa d \kappa$$

 

[nu_paradigm]

Just trying...

$$\int_{0}^{\frac{\pi}{2}} \log \cos \Omega \ d \Omega$$

$$f(x) = \sin x, \mbox{if} \ x \ \epsilon \ (0, \frac{\pi}{2})$$

 

[nu_paradigm]

$$f(x) = \left {\begin{array}{cc}\sin x,&\mbox{if} \ x \epsilon \ [0, \frac{\pi}{2})\\ \cos x, & \mbox{if} \ x \epsilon \ [\frac{\pi}{2}, \pi)\end {array}\right$$

 

[extreme_machinations]

$$F=GmM_e/r^2$$

 

[extreme_machinations]

aaahhaa! now that more like it
hey thanks doc

 

[extreme_machinations]

$$f(x)=sinx^2$$

 

[extreme_machinations]

$$int_{0}^{1} sinlogx$$

 

[extreme_machinations]

$$\int_{0}^{1} sin^2logcosx dx$$

This is a test

Slick!

$$\int_{0}^{1} sin^2logcosx dx$$

Doesn't look good.This one does.

$$\int_{0}^{1} \sin^{2}x \ln\cos x \ dx$$

[lawtonfogle]

please help, i cannot find the 'does not equal' latex equation

 

[dextercioby]

\neq should do it.

Daniel.

 

[lawtonfogle]

$$a \neq b$$

this should work

 

[lawtonfogle]

next question, can i download this for my computer, i have a paper due when i return to school, and it will be a vast help to be able to type the symbols.

Do NOT pay attention to this! (Just the triangle problem)--Do Not pay attention to this!

 

[bomba923]

Do NOT pay attention to this! (Just the triangle problem)--Do Not pay attention to this!

$$A\left( t \right) = \frac{{\left\| {\left[ {\vec r_2 \left( t \right) - \vec r_1 \left( t \right)} \right] \times \left[ {\vec r_3 \left( t \right) - \vec r_2 \left( t \right)} \right]} \right\|}}{2}$$
-----------------
And the coordinate system based on parameter $t$ by unit vectors:

$$\vec u\left( t \right) = \frac{{\vec r_1 \left( t \right) - \vec r_2 \left( t \right)}}{{\left\| {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right\|}} \\$$

$$\vec v\left( t \right) = \frac{{\left[ {\vec r_3 \left( t \right) - \vec r_1 \left( t \right)} \right]\left\| {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right\|^2 - \left[ {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right]\left\{ {\left[ {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right] \cdot \left[ {\vec r_1 \left( t \right) - \vec r_3 \left( t \right)} \right]} \right\}}}{{\left\| {\left[ {\vec r_3 \left( t \right) - \vec r_1 \left( t \right)} \right]\left\| {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right\|^2 - \left[ {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right]\left\{ {\left[ {\vec r_1 \left( t \right) - \vec r_2 \left( t \right)} \right] \cdot \left[ {\vec r_1 \left( t \right) - \vec r_3 \left( t \right)} \right]} \right\}} \right\|}} \\ <br /> \end{array}$$

Again----Do NOT pay attention to this!

Hello everybody

Sorry if this has been discussed already, I couldn't find anything like it:
How can I create a statement like
$$\hat{\xi}(g_0) \longrightarrow \infty \ (g_0 \rightarrow g_0^*),$$
but with the second limit written smaller and below the first arrow?

Thanks, Bruno

 

[dextercioby]

$$\hat{\xi}\left(g_{0}\right)\substack{\displaystyle{\longrightarrow}\\g_{0}\rightarrow g_{0}^{*}} \infty$$

Daniel.

 

[robphy]

Here's a little modification of dextercioby's suggestion.
$$\hat{\xi}\left(g_{0}\right) <br /> \underset{ g_{0}\rightarrow g_{0}^{*} <br /> }{<br /> \overrightarrow{\qquad\qquad} <br /> }\<br /> \infty$$
or
$$\hat{\xi}\left(g_{0}\right) <br /> \underset{ g_{0}\rightarrow g_{0}^{*} <br /> }{<br /> \overrightarrow{\qquad} <br /> }\<br /> \infty$$

 

[kuengb]

Thank you! That's exactly what I've looked for.

[calculus1967]

$$\int_0^5 f(x) dx = \frac{125}{3}$$
where $f(x) = x^2$

 

[dextercioby]

U can use "{}" or "\qquad" or simply "space \ space" to place a space between "f(x)" and "dx".

Daniel.

$$\ln(ab) = \int_1^{a} \frac{1}{t} dt + \int_a^{ab} \frac{1}{t} dt$$

$$s = 1/2(u+v)t$$

 

[KaneOris]

$$s = u+v/2*t$$
