Many innocent people were killed in this tragedy...
I am just struck by this incident. Many of the people whom I knew lost their lives ...
feeling to cry very badly.............
I understood this whole lot somehow but... I am struck still.
I get the value of tn.. Using that table, i get the values of n^2 , n^3 or what ever....
but then bringing out the common???? I am struck at this point in each and every problem.....
I think I can never do this.
this one... Why did you find 2k^2 here?
Why did you try to find the value of
in that?indefinate sum?? And definate sum??? What is this??
We have something as summation of finite series.. I don't know whether it is indefinate or definate?
By this way , we get the answer as
What kind of notation? ?
What wrong did i do in pulling that common out??
Actually , I did not get that step yet .
Is it possible to solve this using the general laws of motion or using Newton's law??? or any other easy way???
I have edited my previous post and completed it.
Please have a look at it.
I am getting confused ..
Another question now, I will come back to this question later.
The Question is: -
Find the sum of n terms of the series:-
I tried doing it this way :-
Am I going right?
Why taking n(n+1) / 6 as common?????
I can see only half of the previous post.. How is it like that?
I copied it correctly. I will check it again
It cannot be like that. It is given in the solved examples section of my textbook. They cannot be wrong
I underlined it. Now please see the bold underlined part. Explain me how they got that there?
I think I did it. What about underline?
\bf for making it bold????
what must I do to it?
some thing enclosed in tag
what about my other question?
it is not given in the problem. How to generate myself?
curve fitting idea???
i know it . But how did they get it as n.2n=1wholesquare???
why does underline, bold function not work here??
Find the sum of 20 terms of the series
Solution:-
Let us find
and then...................
how did they get that
?I have made that part bold.another question, in the next step , how do we get that bold and underlined part there???
Please answer as fast as you can . Thank you.
