integrate 9

Tell me the method i will tell u the ans later.

U draw the graph:
For -2<x<0,
min(x-[x],-x-[x])=x-[x]={x}
=>Area=1/2+1/2=1

For 0<x<2,
min(x-[x],-x-[x])=-x-[x]
=>Area=-1/2-5/2=-3

Total area=1-3=-2
(Hopefully)

visualisng is the main problem here.......[1]

anurag`s method is correct.

otherwise ankit u can even try splitting into much cmaller intervals and then easily get result. and comeon u would be knowing the basic int x and {x} graphs na.
