Solve the equation

for x. You get 2 solutions:

I used the second one.

Hi,

Hope you don't mind replying to old ones, I'll post code whichever I'll be able to come up with!

```
samp=:1000000
f=:1+?samp$0
fx=:2*(1-%f^2)
(+/%#)f*fx
```

Okay, it's very lightweight when compared to other functional programming languages, so I'm fascinated!

Oh sorry, I did not understand. I thought you meant program size.

No problem, i'll explore more into the functional stuff..

I prefer it too but I am afraid that it will always be like a second language to me. When you begin with procedural you are poisoned for life. See you later, got to get off.

myPDF[]=ProbabilityDistribution[2(1-1/x^2),{x,1,2}];

Is that an array construct?

No, that is a PDF. The random variate command constructs an array of random numbers that obey that PDF.

How about writing a CFD simulation or a chemistry one?
