##### Testing Math

Testing how MathJax was hooked up
\begin{align*}
u(x,t)= &\underbracket{\frac{1}{2}\bigl[ g(x+ct)+g(x-ct)\bigr]+\frac{1}{2c}\int_{x-ct}^{x+ct} h(y)\,dy}_{=u_2}+\3pt] &\underbracket{\frac{1}{2c} \iint_{\Delta (x,t)} f(x',t' )\,dx\,d t' }_{=u_1}. \label{eq-4} \end{align*} #### James McVittie • Full Member • Posts: 20 • Karma: 1 ##### Re: Testing Math « Reply #1 on: September 20, 2012, 10:04:04 PM » This is just a test to see whether I can copy and paste from LyX: u(x, t) = \varphi(x-ct)+\phi(x+ct)-\intop_{x-ct}^{x+ct}g(y)dy #### Victor Ivrii • Administrator • Elder Member • Posts: 2607 • Karma: 0 ##### Re: Testing Math « Reply #2 on: September 21, 2012, 02:55:35 AM » This is just a test to see whether I can copy and paste from LyX: u(x, t) = \varphi(x-ct)+\phi(x+ct)-\intop_{x-ct}^{x+ct}g(y)dy Yes, you can but need to switch on math (inline or display respectively) Code: [Select] u(x, t) = \varphi(x-ct)+\phi(x+ct)-\intop_{x-ct}^{x+ct}g(y)dyu(x, t) = \varphi(x-ct)+\phi(x+ct)-\intop_{x-ct}^{x+ct}g(y)dy Code: [Select] u(x, t) = \varphi(x-ct)+\phi(x+ct)-\intop_{x-ct}^{x+ct}g(y)dyu(x, t) = \varphi(x-ct)+\phi(x+ct)-\intop_{x-ct}^{x+ct}g(y)dy Actually I never saw \intop (just \int) and double dollars are deprecated (see my code), but your example works #### Jinlong Fu • Jr. Member • Posts: 6 • Karma: 5 ##### test for math « Reply #3 on: September 23, 2012, 02:38:04 AM » x>b^2, is it the same as latex? local\ mean\ level\ \qquad S_t = \alpha(\dfrac{X_t}{D_{t-s_1}W_{t-s_2}})+ (1-\alpha)(S_{t-1} + T_{t-1}) trend\ \qquad T_t = \gamma (S_t - S_{t-1}) + (1-\gamma)T_{t-1} seasonality\ 1 \ \qquad D_t = \delta (\dfrac{X_t}{S_t W_{t-s_2}}) + (1-\delta)D_{t-S_1} seasonality\ 2 \ \qquad W_t = \omega (\dfrac{X_t}{S_t D_{t-S_1}}) + (1-\omega)W_{t-s_2} \hat{X_t} = (S_t + kT_t)D_{t-s_1+k}W_{t-s_2+k} « Last Edit: September 23, 2012, 02:41:53 AM by Jinlong Fu » #### Victor Ivrii • Administrator • Elder Member • Posts: 2607 • Karma: 0 ##### Re: test for math « Reply #4 on: September 23, 2012, 05:55:35 AM » x>b^2, is it the same as latex? Yes -- except MathJax neither is nor intended to be a complete LaTeX. See http://www.math.toronto.edu/courses/apm346h1/20129/about_mathjax.html Note: If you have text snippet inside of math you should use \text{Your text} rather than format it as math as you did. You can also use \textrm{Your text}, \textit{Your text}. Also DoubleDollars are deprecated in LaTeX, you use \[ or \begin{equation*} \end{equation*} (without * for a numbered version)

PS I disabled  and  as they in the forum environment have funny side effects.
