How to derive from n*x^(n-1) to limit definition ?

I am trying to solve a simple two-equation linear system with solve, but I keep getting this weird result where the magnitude order of the numerator and denominator don't cancel out. Whenever I have a linear system with floating-point numbers, more unknowns than equations and try to solve it for a specific set of variables, this happens.

Any suggestions on how to get around this? Or do I need to solve it manually?

I can display an animated plot of the Normal distribution pdf and was wondering if anybody has a routine to animate the Normal cdf. If this is so - is it possible to generalise for any continuous statistical distribution?

Dear Community!

I'm struggleing with a problem long since. I highly appreciate any help with this theme.

The problem is the following:

- I have a set of points, what comes from a numerical solution of a complex, but periodical function. Therefore I have a set of points (X;Y). The points are doesn't matter, but in my case, it look like this:

I want to use the Fourier-method to approximate this points with a function.

The best result I could get is this:

But it is not acceptable due to the high inaccuracy at the starting, and finishing points (there is a diagram inaccuracy %):

I'm feel like, I'm doing something wrong. Unfortunately, I had no time to look deep into the math here. Can somebody tell me, that how can I get a better result, using this method?

Thank you very much for the help in advance.

Best regards

Hi guys,

I'm trying to apply boundary condition on the seris i generated using Adomian decomposition. Could some one please check it for me?

Hi everyone,

Please, I really need your expertise advice(s) on what i am not doing right in the code attached below. I was actually writing the code on Multi-step DTM, but, instead of continuing from the last point, it starting all over again. Please, your expertise will save a soul here. Regard

Thanks

I'm pretty annoyed with maple because when I try to create proc's it dooes not use tabbing or smart tabbing. This makes writing readable code a chore. Basically it's always screwing up alignment. (it wants to left justify things a lot)...

What's worse is that using the tab key takes one outside the proc rather than adding a tab, making one having to use spaces.

Any way to fix this?

Hello, I try this integral, but Maple not solutions, the answer is the same integral.

int(N*exp((2*(-(1/2)*x^2-2*a^2*ln(x)*x/(-2*x^2+2)))/sigma^2)/(-2*x^2+2), x = -1 .. 1)

N,a, sigma are constants.
