Hi all, I am looking for a low-mid difficulty level calculus book to grasp the main concepts in a short amount of time and to apply to economics problems ie:cobb douglas production function/solow model. Does anyone here have any suggestions as to the best one(s)?
thanks,

I guess what I am trying to get at is that we see landmarks in Mars that conspiracy theorists would argue are man-made structures (ie: the face on Mars). So, there could've been life on Mars previously, intelligent life. Now what are the arguments that non-conspiracy theorists have for that...
I am not a student of astronomy or physics, or any sciences for that matter. But I do have some things I wish to ask the scientific community here in the hopes of better understanding all of your viewpoints as to the title of this topic. First question:
a. Assume that Earth is about to face a...
How about burning of propane. C3H8 + 5O2 ---> 3CO2 + 4H2O + heat
The entropy does increase in this rxn, due to 7 moles of gas in products vs. 6 in the reactants. However, C3H8 is relatively more complex relative to all the other molecules in this rxn. So how can I be sure whether entropy of...
Homework Statement
A. Explain the need for Gibbs Free Energy equation.
B. Explain what it means when:
\Delta G <0 \Delta G >0 \Delta G =0
Homework Equations
\Delta G= \Delta H-T \Delta S
The Attempt at a Solution
A. Gibbs eqn comes from the need to calculate the entropy of...
david90: The background noise comes from the speaker only at high volume and even then I can only hear it if I hold my ear 10cm near the speaker. I tried the earphones on my MP3 player and also Home Stereo and it works perfectly well.
Ouabache: It is static noise, without intermittance...
It is loud enough to cause a serious distraction but not as loud to cause the ear to hurt, although prolonged exposure could cause the ear to hurt. It does vary with the volume.
This may not entirely be a physics question but I know physicists here might know something about it. If it seems to be irrelevant then please delete it.
I have a speaker and a earphone. When I plug the earphone into the speaker's earphone jack, I hear a constant background noise, even when...
Yes, since the pendulum had gravitational potential energy relative to its position before, all of the gravitational energy plus that little kinetic energy given will be converted fully to kinetic energy when the gravitational potential is zero which is at the bottome as you say it
How can I solve these two problems?
P(n,3)=210 and P(5,r)=20
For the first one I got up to n(n-1)(n-2)=210 but I don't know how to solve a cubic equation...And the second one I have no clue. I'd appreciate some help, thanks
