in series
what is the meaning of the first point in the syllabus
i know abt the factorial what abt the other thing , cant type it

and what is the meaning of condition for the convergence of a geometric progression!

 

[intel1993]

in geometric progression the common ratio (r) must be between -1 and 1 then its some to infinity will exist so then it would be convergent .........

 

[princesszahra]

thanx
any i would also like to know abt definite integral and improper integral

 

[intel1993]

wat u wanna knioe abt dat.....???

 

[princesszahra]

any example solving question of this type will be enough for my understanding

 

[intel1993]

basically improper integral is the integration which we do without any limits of (x)

n definite integral consist of the limits of the value of (x)
as we have seen in the volume and areas question.....

Find the area under the graph fbetween x=1 n 3.....

this is the basic concept.....

Actually, Improper is not limited to not having any limits, it may also be an integral that goes from a value to infinity (asimptote) or one that has 0 as a limit too.

I might be wrong but i think if the ratio is greater than 1 then it can NEVER converge. Sum of infinity is only for those whose ratio <1 (ie the convergent ones). That applies to all the past papers i've solved.
