# Integration help requested watch

1. r is an integer taking values from 1 to 10. f(x) is {pdt.(x+r)}*{summ.(1/x+r)}. f(x) is integrated from x=0 to x=1, and the resultant value obtained is m. Find m.

MAN ALIVE!

I am solving PDEs at the moment and they are nothing compared to this.

I can only think of doing the actual integration, and I can only think of integration by parts under these signs

Need time ... and a brain transplant

Brain is thinking
reduction formulae (repeated integration by parts)
change into Beta Functions (limits)

Umm, and what might be beta functions?

probably not needed here (it is an integral function with identical limits to yours)

Haven't had a chance to look at it properly as this requires serious thinking
(I can tell you that the answer is 10 .10! so O know what the answer is but I cannot prove it)

I am very busy to be looking at hard maths today but I will look at it tomorrow afternoon

Thanks! Your help would be most appreciated!

it is done by integration by parts

differentiate the product (logarithmic differentiation)
integrate the sum

still after that is disgusting

let me know if you manage it ok.

beautiful question... (+5)

No, I couldn't manage it. But then, I checked out the Q online , it was summ.(x+r), not summ.(1/(x+r))

I managed it correctly to 10 x 10!
as it was printed on the paper

I would love to but posting full solutions is not allowed in this site. As I do not feel I am very popular here I run the risk of being reported ...

I already added the question in one of my booklets
(it willbe the last question in this link http://www.madasmaths.com/archive/ma...ons_part_i.pdf)

Do not download it yet because although I have updated the booklet in my computer I have not uploaded it yet in the site. I am planning to upload in about 6 hours.

hope you can wait

no worries

you will see it in the morning

it is Q208

It takes a long time to download as it is a very big file.

Goodnight.

EDIT: I just updated 21.34 GMT your question is on line
