Homework Statement
does the series e^n/2^n converge or diverge?
does the series 2^n/e^n converge or diverge?
The Attempt at a Solution
I took lim→∞ e^x/2^x and am getting ∞, so it diverges, right?
I also used L'Hopital's rule and got the same result.
My prof hinted that I was...
Thanks for the reply.
cool, I see how to get b^2 using trig ID's.
But adding the sums of the right hand I'm not seeing the algebra.
and seeing how this equation:
b^2=c^2sin^2\theta+c^2cos^2\theta-a^2sin^2\phi-a^2cos^2\phi
gets to this equation...

The Attempt at a Solution
I don't have a problem finding the answers, but the other steps we need to show are giving me a hard time...
Thanks for your response! I guess I am looking for experience or thoughts rather than advice.
What actually makes it so difficult (aside from just being a challenging major)? Memorizing? Work load? Comcepts? A combination of things?
I have a strong work ethic, but I've heard...
I've been working on my 2 year transfer degree at the local community college in order to head to a 4 year for mechanical engineering. After a few chem classes (which are req'd for ME anyway), I find it really fascinating and kind of fun.
I've started toying with the idea of switching to a...
Please, any help would be appreciated. I'm not looking for an answer, just a push in the right direction. Here's what I've tried to do to start out:
-put integral in terms of V
-break down Volume values and try to solve for r and h
-ratio between starting values: 100lb/in^2 and 400in^3
?
Our professor didn't say we needed any special formulas or anything - that we should know how to do this from our previous section's lessons. Where do I start? That link shows more variables than I have (I think) like lambda values, etc.
