Fullscreen mode, n-th roots

Today we have to new examples:

  • https://jsxgraph.org/wiki/index.php/Fullscreen_mode: The user can click on an icon in the JSXGraphnavigation bar on the lower right or click on an external button provided by the content creator to display a JSXGraph construction in full screen mode. This can be useful in classroom situations
  • https://jsxgraph.org/wiki/index.php/N-th_root: it seems to be a much requested feature to be a able to plot the cube root function or in general the n-th root function, where n is an odd integer, also for negative values. This is enabled by the new functions cbrt(x) and nthroot(x, n)
