Calculus

[lghickman21]

Anybody good with calculus? I need a little help

[Fred55]

im alright, whats the problem

[lghickman21]

does the series of E (1/(n * sqrt ln(n))) from 1 to infinity converge.

[Fred55]

can you rewrite that any better? is it e^(1/n*sqrt ln(n)) or the series 1/n*sqrt ln(n)


can you scan the problem from the book

[lghickman21]

the series 1/n*sqrt ln(n) is what i meant.

Over the epsilon would be infinity and under the infinity would be n=1. if that helps.

[Fred55]

use the integral test, and it actually integrates quite nicely, and it does diverge.

[lghickman21]

sweet thanks!

[lghickman21]

alright i can't do the integral. it is too late or something. can you help again.

[Fred55]

do a U substitution with U=ln(x), that shoudl clean it up

So yeh im studyin for finals and its absolutely killin me. Id do anything to be ridin this week. But i cant seem to figure out how to do this problem

y=x^2 a=-2 b=2
your suposed to find the area of the regoin under the curve of y=f(x) over the interval [a,b] divide the interval into sub intervals, calculate the area of the corresponding circumscribed polygon and then let n--> infinity. I have no clue how to even go about starting this.
