I am just started learning beamer. For my presentation I want to make a slide to show a animation for my +2 students. I want to explain the concept of convergence of sequence. enter image description here

I want to explain it for the the sequence {1/n^2}. I will choose epsilon=1/100.I want to draw Y axis labeled as real line. I want to plot the graph of y=1/x^2 restricting the domain to Natural Number. I want to show the points for n=1(y=1) to n=9(y=1/81) of the graph and want to animate so that points will get projected on corresponding Y axis.(for n=5, graph point is (5,1/25)...it is to be projected to (0,1/25) so onenter image description here)

It would be a great help if someone help me creating the code. I know "geogebra" is a 2d drawing software that would generate the tex code to export it in beamer file. But I don't know how to animate it in terms of overlay specification. I complete help is very very welcome. Also it would be a great help if anyone indicates some resource/link that will help me learning how to create this type of simple animation.

    Welcome to TeX.SX! Please post what you've got so far as MWE. – TeXnician Apr 14 '17 at 9:19
  • I am not getting. MWE meaning? – Tom Apr 14 '17 at 9:21

    A minimal working example, e.g. a pgfplots plot or something what you've done and tried so far (there are some posts on this site which would at least explain how to do the plot without overlays). – TeXnician Apr 14 '17 at 9:23
  • I dont understand.... – Tom Apr 14 '17 at 9:30

    Welcome to TeX.SX!. Please add a minimal but working example of the code you already have for the plot into your question (not into a comment!). This means code starting with \documentclass and ending (after some preamble code, \begin{document} and some body code) with \end{document}. – Schweinebacke Apr 14 '17 at 11:19
