mathjax

问题 In Mathjax, how do I write this as a two-liner separated by the second = ? This is the Mathjax code: $= 2[2W(k-2) + (k-1)2^{k-1}] + k2^k= 2^2W(k-2)+(k-1)2^{k-1}+ k2^k$ What do I need to change to add a new line before the second = sign? 回答1: Use \\ for Mathjax newline. Way easier than expected, plus this was already answered here - http://meta.math.stackexchange.com/questions/11720/new-line-within-mathjax $= 2[2W(k-2) + (k-1)2^{k-1}] + k2^k\\= 2^2W(k-2)+(k-1)2^{k-1}+ k2^k$ ^^ slashes here 来源：

问题 This is a TeX legacy issue---it would have made more sense to require a whitespace when a whitespace is desired: 12,123 is probably a number, while 12, 123 is probably a list. Alas, it is what it is. Related to MathJax rendering of commas in numbers, where the solution is suppression of spaces via {,} . Works, but inconvenient. Is there a way to make this automatic? The hack in https://github.com/mathjax/MathJax/issues/169#issuecomment-2040235 is concerned with European vs Anglo. The

问题 How do I achieve the same effect in mathjax? Inserting, \DeclareMathOperator{\E}{\mathbb{E}} in the html does not work, mathjax throws Undefined control sequence \DeclareMathOperator error. I can, however use `newcommand. Is there a workaround? 回答1: You need to load the AMSmath extension (which is included in all the pre-defined configuration files, so I'm assuming you are using your own configuration). Add TeX: { extensions: ["AMSmath.js","AMSsymbols.js"] } to your configuration and that

问题 I use mathjax on a website, and I'm building a little javascript web app. Mathjax is configured so that when text is surrounded with dollar signs, like $10^2$, it is converted to a math format. This works if I insert the text in html. ie: <div id=mathDiv">$10^2$</div> displays 10 with a superscript 2. However, if I insert this text via javascript, I don't get a 10 with a superscript 2: document.getElementById(mathDiv).innerHTML = "$10^2$"; returns the text $10^2$ I know this is a simple

问题 Uiwebview taking huge amount of time to load html content in iOS 7. The html content has mathjax library. Its working good in iOS 5.1 and iOS 6.1. Can you please help me how to fix this issue? I am using loadRequest method to load html content into UIWebView. Thanks, Rahman 回答1: I have the same problem. After the update to iOS 7, the loadRequest takes about 10 seconds (with iOS 6 less than a second). My code is like : NSString *whichWiki = @"http://en.wikipedia.org/wiki/"; NSString *keyword =

问题 i want set expresion of stack to mathjax (dynamically) this is my stack var showStack=[]; showStack.push({ Key: 'topic', Value:"سرمایه" }); showStack.push({ Key: 'operator', Value: "+" }); showStack.push({ Key: 'topic', Value: "مالیات" }); showStack.push({ Key: 'opeator', Value: "/" }); showStack.push({ Key: 'number', Value: "8569" }); showStack.push({ Key: 'opeator', Value: "-" }); showStack.push({ Key: 'topic', Value: "اندوخته قانونی - سال قبل" }); and this code create my fomula from my

问题 With knit2html() from the knitr package, I can generate html pages that contain latex equations and R code. But on my system equations are not rendered when using RStudio's "knit html" button. It is because I have modified the way the "knit html" button works. To include a table of content on my html pages, I followed the Rstudio advice on Customize Markdown Rendering. And created an .Rprofile file at the root of the project directory that overrides default markdown rendering options. My

问题 Im developing an application that shows a mathematical expression in function of the content of a form. The webpage show the different states of the expression while its rendering, and I would like to show only the last state. I have already hidden the mathematical expression while its shown in Tex language while MathJax is rendering. But there are still two states more: Processing : The expression is in a bigger font. Typesetted : The final version, in a smaller font. Im trying to hide one

问题 I have a strange problem. I am trying to render the following valid latex, $$\int_{x=0}^{x=h} u_t dx = \int_{x=0}^{x=h} (-au + du_x)_x dx + \int_{x=0}^{x=h} s(x,t,u) dx$$ in a markdown cell in an ipython notebook (version 0.13.2 built from source). If I instead render each term separately it works! $$\int_{x=0}^{x=h} u_t dx $$ $$\int_{x=0}^{x=h} (-au + du_x)_x dx$$ $$+ \int_{x=0}^{x=h} s(x,t,u) dx$$ Is it possible to get an error message to find out where the problem is? iPython is rendering

问题 I've spent days about how to render MathJax into PDF on client-side only (using several libraries like jsPDF, etc.) for the open source project Writing. I have tried many different options, without any success. Here is a code showing the problem in my latest attempt, based on this answer. MathJax.Hub.Config({ tex2jax: {inlineMath: [["$","$"],["\\(","\\)"]]} }); document.getElementById("getPdf").addEventListener("click", getPdf); function getPdf() { var svg = document.getElementById('main')
