Hello all
y = \frac {1}{4} x^4 - \frac {2}{3}x^3 + \frac {1}{2}x^2 - 3
Find the exact intervals in which the function is
(a) increasing
(b) decreasing
(c) concave up
(d) concave down
Then find
(e) local extrema
(f) inflection points
So I found \frac {dy}{dx} = x^3 -...
Hello all
If you are given the function y = x - 3e^-x^2 and you want to find the intervals where the function is increasing and decreasing, concavity, inflection points and any local extreme values, would I first find the derivative?
My work
If f(x) = x - 3e^-x^2 then f'(x) =...
Let say we have a sliding box. The box is sliding because of an constant force perpendicular to the box. There is no friction and no air restistance. Does the speed of the box increase or is it constant. ?
Folks,
This is the solution I have for a problem in my textbook regarding sequences. I just need to know whether I have the right idea in mind.
Thank you very much!
We can use an analogus function to show that the sequence given by
a_{n+1} = \sqrt{2+a_n} \quad a_1 = \sqrt{2}...
I partitioned my hard drive into two sectors (I installed windows on one).. it turns out to be too small (sp2 makes a backup of the whole system :rolleyes:).. I'm at a loss how to redistribute the size though :rolleyes:
Anyone a clue? I'm running Windows XP (I guess I need to go into BIOS at...
As a neutron star collapses further and neutron degeneracy pressure causes
neutrons to increase in mass (by virtue of high speeds),
if that mass increase weakens the force of gravity it could stop
a singularity from forming.Is there any evidence that particles with large mass
increases due...
I'm having trouble getting the answer without doing a guess and check.
Q: Find the maximum angle a projectile can be shot so that it's distance from the origin is always increasing. Air resistance negleced.
So there is the x and y position based on initial velocity, angle, and time, but I...
This has to do with global warming, and a new solution to cooling buildings in Toronto. I read today where the near freezing water from the bottom of Lake Ontario will be channeled into large buildings in Toronto to cool them, thereby decreasing the need for traditional, air conditioning, and a...
I'm furious with Matlab. when I reach a 1*10.000 array or similar figures it says to me: "out of memory". Does anybody know how I can do larger the virtual memory dedicated to this programe?. I have a 40 GB and 500Mb RAM computer, so it would be enough for eating anything!.
if you take a laser and shine it into another set of mirrors so that the light shoots out of the opposite end through which the laser first went into the second set of mirrors, would it be more powerful than when it started (the second set of mirrors would have a lasing medium)? if so, could you...
hey guys what's up?
just recently I've been working on this potato battery thingy in chemistry class and the highest i can get it is 15 volts. i knwo there are a lot of variables involved but are there any suggestions that you might think would help achieve a higher voltage? i was thinkin of...
Every time a measurement is made – the methane level rises.

The first of my two questions concerns the aspect of SR that deals with the mass of an object increasing as is moves faster and faster (or more appropriately, as the energy gets larger and larger). I'm a novice when it comes to higher level physics, and everything I know comes from reading books...
According to the best current data available to cosmologists today, the universe is not only expanding, but the speed of which it does so is increasing. This is well-known but the cause for it is not.
There are many different theories, from dark matter and dark energy to ideas revolving...
The number of registered cases of whooping cough in the United States has increased significantly. Especially children under the age of 5 months are at the most risk, since they haven't been fully vaccinated against the disease.
The number of cases was 19,798 in the '90s, an increase of 49%...
The Graph above shows the speed of a car traveling in a straight line as a function of time. (Sorry no graph) The car accelerates uniformly and reaches a speed Vb of 3.20 m/s in 8.00 seconds. Calculate the distance traveled by the car from a time of 1.80 to 3.60 seconds.
Im not sure what...
Let's say that there is a spoked wheel but the spokes are tubes with freely moving masses inside and that there is no friction. Given a certain fixed angular velocity, what I want to find is the final radius after a certain angle of rotation (assume 270 degrees). An assumption is made that the...
