Animating rows of equations to look like manually written by hands step by step












2















I want to animate rows of equations to look like they are manually written by hands on a piece of paper.



Requirements




  • The equations must be decorated with minimal numbers of cluttering animating decorators.

  • For each frame, the first part of an equation sticks to the left and the subsequent parts of the equations flow to the right. (Rather than the first part starts from the center and it get pushed to the left when the subsequent parts come).

  • we can also animate fraction, integral, limit, etc. For example, frac{a}{b} will be animated to produce a followed by a horizontal line and followed by b. Another example, int_a^b will be animated as an integral sign followed by b that is followed by a.


  • To make it more portable, not using beamer is preferred.



Question



How to achieve such requirements? I will give a bounty of 2000 for those who can provide me with a satisfying code. Any additional features from your creativity is also welcome!



MWE



Warning: the following code will spin undefinetely.



documentclass[12pt]{beamer}

usepackage{amsmath}

usepackage[active,tightpage]{preview}

PreviewBorder=12ptrelax

PreviewEnvironment{align*}



newcounter{counter}

newcommand{foo}[1]{stepcounter{counter}only<thecounter->{#1}}

begin{document}

begin{frame}

    begin{align*}

    foo{a}foo{+b}&foo{=1}\

    foo{frac{1}{2}}foo{+frac{3}{2}}foo{=2}

    end{align*}

end{frame}

end{document}

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

          Calculate evaluation metrics using cross_val_predict sklearn

          Image
          1 In the sklearn.model_selection.cross_val_predict page it is stated: Generate cross-validated estimates for each input data point. It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean? If this gives estimate of Y (y prediction) for every Y (true Y), why can't I calculate metrics such as RMSE or coefficient of determination using these results? python scikit-learn cross-validation share | improve this question edited Nov 28 '18 at 17:52 desertnaut 20.3k 7 43 79 ...
