Question

how to graph {x}=2y?
{x} is the fractional part of x..i.e x=[x]+{x}

Answer 1

start by doing the graph of {x}=2y on the interval [0,1) first

Answer 2

in the interval [0,1) we have x=2y

Answer 3

then what, watchmath?

Answer 4

Then what happen in [1,2) ? :D

Answer 5

i saw the graph in wolframalpha..but doesnt make sense!

Answer 6

The value of {x} on [2,3) is also [0,1)

Answer 7

in [1,2), we have x-[x]=1-1=0 for x=1, x-[x]=1.1-1=0.1..and so we have the smae graph x=2y

Answer 8

so we have x=2y in every such interval:) am i right?

Answer 9

Yes, to be precise line segment of the same slope

Answer 10

thnx..:)
