Don't use this unless you really have to. Non-math posts regarding the subreddit itself. So I was hoping somebody here would give me a nice simple explanation. Use when linking to any site, including Imgur, that is not . What is the volume of a 4D sphere I've seen so many sites that would have answered this question, but all of them have so many numbers that some people (including me) don't understand. To help with the geometry we built some models using our Zometool set. My goal today was to help them get a slightly better understanding of how we move from zero dimensions to 4 dimensions. "Reddit Did The Math", linking to a comment or post on Reddit where someone else does the math! Thought I’d be shoveling snow tonight so we moved on to our next talk about 4D spheres this morning. You did the math and want to share it! Asking the /r/theydidthemath community to do the math for you! Please keep them at the start of your post. Here are the tags we accept and what they are for.
#VOLUME 4D SPHERE HOW TO#
If the above equation looks like garbled code, or for information on how to display subscripts and superscripts, check our wiki page. The projection of a hypersurface into 3D space is a 3D volume. Superscripts and subscripts are supported in this subreddit, and LaTeX is used here as well. A 4D solid can be displayed by its boundaries which are hypersurfaces. In a 4-dimensional spacetime, we can define 1-volume (length), 2-volume, 3-volume, and 4-volume. Be sure to include the reason for your report! The output of the 4D raytracer is a gridded 3D volume of RGB triples, analogous to the gridded.

When answering posts, please cite reputable sources to defend any evidence that cannot be proven using your own math. Jokes or off-topic top-level comments will be removed. Also, don't be a dick.ĭo not submit top-level comments in posts that are not an attempt at an answer or a request for clarification. Reddit's site-wide rules still apply here. Repeat or egregious offenders will be banned permanently. Rule breaking posts/comments will have a temporary ban that will serve as a first offense "warning". There is no warning for hate speech of any kind. This subreddit has a zero-tolerance policy for hateful or unnecessary language. Try /r/homeworkhelp or /r/cheatatmathhomework instead. Posts which seem to be asking for help on homework will be removed. The formula for its surface volume is 2(pi2)(r3). The four dimensional sphere is a unique object, with properties both similar. The formula for its interior volume is V (1/2)(pi2)(r4). An interior volume, which is 4 dimensional, and a surface volume which is 3 dimensional. For more abstract math, try /r/math or /r/learnmath. A 4 dimensional sphere has two 'volumes'. Posts containing "simple math" will be removed, as well as requests whose answers are easily searchable online, and any other post at the moderators' discretion. How many feet are in a mile?) use Wolfram|Alpha™. " /u/FragTheWhale calculates.".įor easy and quick math results (ex. Give credit where credit is due-include the user who made the calculations in any post you submit: ex. posts must have a calculable answer otherwise, they will be removed. Similarly, to find the 4-volume of a 4-sphere, we integrate over the 4-volume of infinitesimally thick 4-disks that 'make up' the 4-sphere. State clearly what is being or what you want calculated in the title. Proper title tags are required for all posts or it will be removed! The tags accepted are at the end of the sidebar down there.
