Homework Statement
Two equal masses are held on a frictionless track by 3 equal springs, attached to two rigid posts. If either of the masses is clamped, the period (t=2pi/w) of one oscillation is three seconds.
If both masses are free, what is the periods of oscillation of both normal...
Homework Statement
I have a function a_{n}=\frac{2+3n}{2n+1}, and I have to find out whether it converges or diverges. I did the ratio test lim_{n\rightarrow\infty}\left|\frac{a_{n+1}}{a_n}\right|. And according to the divergence test, it should diverge. Then it asks if the series...
Homework Statement
The question states:
Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line.
The lines are, y=lnX, y = 1, y = 2, and x = 0, rotated about the y-axis.
I know how to integrate it, I just don't exactly know which...
