Hello,
Thanks for the reply and sorry for the confusion.
I think a pareto like distribution from 0 to 1 is what I'm going for.
So would I just have it be bounded between 0 and 1?
Thanks!
Hello and thank you for taking the time to read this.
I am making a number generator that generates a number based on a pareto distribution.
The problem is, the distribution essentially goes from 0 to infinity. How would I go about scaling the values so I get a range between 0 and 1...
Hi all. Thank you for taking the time to read this. I am currently studying Grobner Bases and I've been given a problem that I'm struggling to find any resources for. I am interested in find if a certain n for the n queens problem have solutions. Now there are SAT solvers and such which can...
Well what confused me is the inequality. I understood the expression when it has the equal sign, but the problem that was given was |z+i| \leq 3 so I was trying to find a way to change it into simply an equals sign.
Thanks, I see what you mean now. Do you have any advice on approaching a...
Yes that makes sense but how do I show that graphically? I tried changing it to \left.|z| + i = 3 is simply because I thought that would help make graphing it easier? Could I also say it is a circle with the radius of 3-i?
So should I be transforming these z's into their components such that...
Thanks for the reply! I understand what you mean, but would that be the extent of "showing". I guess sometimes I'm just not sure how to properly write these proof type problems.
On a somewhat related note, I'm suppose to graph
\left.|z+i|\leq3 and \left.|z+i|\geq3
I know that normally, if...

Hello! I'm lost on how to start this, I've got formulas given to me from the text, but I have no idea on how to piece everything together. So I need to use established properties of moduli to show that when \left.\left|z_{3}\right|\neq\left|z_{4}\right|,
then...
Hello!
I've been working on this problem and was wondering if someone could check if I've done the rest of this problem correctly!
So after finding the roots, I apply the initial conditions where:
\left.\widehat{u}\left(\omega,0\right) = \widehat{f}\left(\omega\right)
since t = 0, I...

Hi, So I'm suppose to solve the following problem:
\left.\frac{d^{2}u}{dt^{2}}-4\frac{d^{3}u}{dt dx^{2}}+3\frac{d^{4}u}{dx^{4}}=0
\left.u(x,0) = f(x)
\left.\frac{du}{dt}(x,0) = g(x)

The Attempt at a Solution
First I use fourier transform on...
It definitely does not. So I did a bad job in choosing the appropriate time interval then? My graphs definitely made me think I'd be getting answers for nonmoving x values...
That's because we were to graph 10 plots at various t, I decidedly went t=1..10 and from the graphs the roots looked stationary
Also I had the impression that the problem would've been simpler in terms of all the trig stuff...
But in this case we don't know what f(\alpha) is though? You're saying to find all the values of f(\alpha) that gives us zero right? is f(\alpha) u(x,0)? when solving for the equation we had learned to use u(x,0) = f(x) and the derivative of it to be the velocity so...other than that where does...
I understand the reasoning but I am having troubles translating the meaning into math. I mean I set the expression to zero but mathematically, how does "for all values of t" fit in.
This is what I'm thinking currently:
\left. 0 = 2087-16500\alpha^{2}+32928\alpha^{4}-18816\alpha^{6}
This is...
Is there a thread where I can ask questions about maple because I've been searching the internet trying to find out how to factor the polynomial and was unable to find an answer. Apparently the Factors command is suppose to factor multivariate polynomials but when I type in the command to...
Ok so for the x terms I ended up double checking my previous expansion(fixed the mistakes) and then substituted for the x terms. I also used
\cos^2\theta=1-\sin^2\theta
and combined some like terms after multiplying stuff through and got the following:
\left.-\pi sin(\pi...
I've only started using maple until recently but I entered my original derivative, and I right clicked on it and told maple to expand it?
I got the following:
\left.-\pi sin(\pi x)sin(\pi t) - 6\pi sin(3\pi x)sin(\pi t)cos^{2}(\pi t) + \frac{3}{2}\pi sin(3\pi x)sin(\pi t)
\left.- 1344\pi...
so I'm kind of stuck on converting my function using multiple angle formula. This is the formula I found:
\left.sin(nx) = \sum^{\frac{n-1}{2}}_{k = 0}(-1)^{k}\left(\stackrel{n}{2k+1}\right)sin^{2k+1}xcos^{n-2k-1}x
so if my n is \left.7\pi, how does the summation work since...
So if I take the derivative of the function in respect to time, then
\left.\frac{du}{du}(u,t) = -\pi sin(\pi x)sin(\pi t) - \frac{3}{2}\pi sin(3\pi x)sin(3\pi t) - 21\pi sin(7\pi x)sin(7\pi t)
so now I set it equal to zero:
\left. -\pi sin(\pi x)sin(\pi t) - \frac{3}{2}\pi sin(3\pi x)sin(3\pi...

Hi!
