This is Day 10 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210 Based on gregsmith_to's request in the comments, (http://www.thingiverse.com/thing:227223/#comments), for today's equation, I'm doing the Sinc function, y = asin(bx)/(b*x), which is used in signal processing (see http://en.wikipedia.org/wiki/Sinc_function). I've uploaded two different versions of the equation, with different ranges. Per another request, I've included the Openscad file in case someone wants to modify the text or stand. Details: As always, I'm going to continue to post one equation per day until get bored or people lose interest. If there's a particular equation you'd like to see, leave a comment and I'll give it a shot.All files can be printed without support. Photos shown were printed on a Replicator 2 and sliced using the standard setting on Makerware.
Daily Equation #10 - Sinc Function - y = a*sin(b*x)/(b*x)
