thanks for the help

It's actually 1/e :smile:

Hi, I am at an intermedate step of a larger problem and I need to find the following limit: lim(k->infinity) k^k/(k+1)^k I see what this equals (by using computational software) but I am not sure how to show this. Any help?

any chance at a little help, I've done the rest of the problems but I really need to figure this one out by tomorrow. any help is greatly appreciated.

hmmm, the only thing is, the problem gives no indication of the number of samples. it would appear that we have to look at the error function (integral of the gaussian distribution), but I'm still not sure what exactly is necessary. to be honest, everytime I think about this problem I seem to...

Here is a question I can not seem to get from an error analysis course. Assume that you have a box of resistors that have a gaussian distribution of resisances with mean value mu=100 ohm and standard deviation sigma=20 ohm (20%resistors). Suppose that you wish to form a subgroup of resistors...

Why is it that a proportional controller will always result in an offset error?

I have collected 5000 points of data from a sensor on a rotary arm (which I was trying to control to move with a position time graph that follows the pattern of a square wave) My question is, once I've plotted the graph in excel, how can I overlay a perfect (theoretical) square wave to show...

any other suggestions people? I still seem to be having trouble

I have this calculus challenge problem (found here: http://firstyr.appsci.queensu.ca/apsc171/chall1.pdf ) I was able to answer part a and b, however I am unsure how to approach c and onwards does anyone have any suggestions?

For a launched projectile, what are the following theoretical relationships/proportionalities: variation of range with speed of projectile, keeping a constant launch angle variation of range with launching angle, keeping the launching speed constant thanks for the help

For projectile motion, how does one take air resistance into consideration? I have constructed a device to launch a projectile and I know how to deal with projectile motion without any air resistance, but I am unsure how I determine the range (the distance the marble/object will go) in the...
