First,
second, note that in the first interval (integral)
in the second interval (integral)
and so on, unitil
the ath integral , so
as desired.
Hey I'm stuck on this Q and I would be grateful for any replies.
I have tried twice to write the problem in latex but unfortunately I am not proficient enough in it.
I have attached the Q NB it is Q2 on the attached photo
Also I have attached the graph that I think is right for the first part
but my real Q is for part 1 how do you show that that integral is equal to that sum? I can see it clearly from
the graph but I don't know how to show it?
I'll work on part two later.
I would be really grateful for any replies.
Thanks from James
Ok, again we have
as the fisrt part we know the value of on each interval, that is
All the integrants are constants and the lenght of of each interval is 1 we have
The later series is finite geometric series and its sum gives you the result
I just love your forum.Thanks for posting it.Web Development it have something that someone comeback again….there is a lot of useful information a person can get from here…I must say,well done.Free Legal AdviceA good forum with great discussion and a good users,which contribute in the forum.
