I searched about draw graph of $[\sin x]$ but I don't know how to draw it like this: image

I have matlab and gegebra but I don't know how to do it (about points like $\pi / 2$. Is it possible to help me?
I'm sorry for ask this question in this place but I didn't found any better place.

Update: It's gegebra screenshot:
gegebra
Thanks.

  • To clarify: do you really want $[\sin x]$, i.e., the floor function applied to $\sin x$? Also, are you interested in drawing by hand, or only with software? – Matthew Conroy Dec 05 '16 at 20:54
  • I want the floor function applied to sinx with points like $\pi/2$ with value for check limits and etc. I can draw it but It's not main function. my main function for check limit is $[\sin x][x]$ and I need app for draw it exactly with points. – Ali Dec 06 '16 at 02:19
  • You could always add those points (such as $(\pi/2,1)$) separately. – Matthew Conroy Dec 06 '16 at 02:58
  • Yes. we can do this but sometimes I can't draw a graph so I want to check this points with app but that app doesn't show me that points and I can't test all points to find them. maybe this point like $\sqrt3 + 1$! – Ali Dec 06 '16 at 12:07

there are two ways of measuring angles: degrees and radians

in degrees, the wave repeats every 360 degrees, but in radians it repeats every 2 pi, this piece of software is using radians as is fairly standard for higher levels of mathematics (note, wolfram alpha also uses radians)
