Hi all,
I've had an itching lately to dive into something new. Currently, I am a professional computer programmer but have always been interested in astronomy. I took an astronomy course (as well as a lab for it) when I was in college and I remember enjoying it all immensely. I want to get...
I do not understand the pseudocode very well either but I can help...
So you got an integer array. And you're looking for a certain number in the array. So this module is suppose to take care of that.
How would you traditionally sort through a list of things if you were looking for a certain...
Suppose the current drain (on average) of a LED is 2mA at 4.5v. Now suppose that 250 mAH 1.5v cells are being used to power this thing. I want to keep this LED powered for 504 hours (3 weeks), how many cells are needed and how should they be arranged?
Now, here is my stab at the problem...
OK, I am having no problem with the concepts here but just with a particular problem. I have analyzed this problem to bits and nothing is working. Here is what we have:
The bending capabilities of plastic sheets are investigated by bending sheets at increasingly large angles until a deformity...
I graphed the left side of the equation and then graphed the other side (p being X). They do not intersect anywhere. Guess my CDF (Cumulative Distribution Function) is wrong.
Ug and to think I got straight A's in all other Math courses so far. This one is just ridiculous. Never take...
I guess I need to find the expectation value for the second problem first before doing anything, so:
integral of x*2x = integral of 2x^2 = 2x^3/3 between 1 and 0 = 2(1)^3/3 = (2/3) = .75
So from there I would just say (.75)^3 as the answer for the expectation value for Y = X^3?
Trying to solve for x here...
(e^10-11)^-1*(-e^(10-x)-e^10-x) = p
So I try:
(-e^(10-x)-e^10-x) = (e^10-11)p
e^(10-x) = -(e^10-11)p-e^10-x
ln(e^(10-x)) = ln(-(e^10-11)p-e^10-x)
10-x = ln(-(e^10-11)p-e^10-x)
I get stuck there and don't know what to do. Any help appreciated.
Having a lot of trouble with a particular problem in the topic of variance. The problem is:
"Suppose you are organizing a game where you charge players $2 to roll two dice and then you pay them the difference in scores. What is the variance in your profit from each game? If you are playing a...
Hey guys,
I'm in Computer Science and was interested in trying out working at a lab (and actually doing programming work). I was wondering where I could find such a job at these days? I'm pretty sure my university only hires grad students for that kind of work if anything. I will be a junior...
