How do I draw graph of 1/({x}+1)^2 ?

Whenever you need to integrate fractional part type equation then you have to break the integration about integeral values and then integrate
For example for integrating {x} from 0 to 1.7
Then in interval 0 to1 it is x
In interval 1 to 1.7it is x-1
So integrate x from 0 to 1 and add the integration of x-1 from 1 to 1.7 in it

How did you break the limits into 0 to 1 ?

@Raghav_2020 because area covered by x from 0 to 1 is same as area covered by x-1 from 1 to 2 and so on
Basically area covered by {x} from 0 to 4 = 4 area covered by {x} from 0 to 1

With similar reasoning you’ll get the above result

Ok. Thanks
