Yes, the legend says: "(x from -1 to 1)".
The question is, do you know how did Mathematica arrive to that result (5*10^6 - 2*10^7), and if you do, then can you please explain the steps and calculation behind it?
I wrote this: {x, 0, 0}/|x|^3
That expression evaluated here: http://www.wolframalpha.com/
...produces the result as I described it. The question is if you know how did Mathematica arrive to that result, and if you do, then can you please explain the steps and calculation behind it?
That is yet another way to say the same thing, apperantly, but then, I guess, the original result might actually be correct after all. Who is the judge?
What is the meaning of this: {x,0,0}/|x|^3 = (20^7, 50^6) ??
When I plug in this "{x,0,0}/|x|^3", here: http://www.wolframalpha.com/
...it plots some range for x=-1 to x=+1, and it plots values from 5*10^6 to 2*10^7.
What does that mean and where did those numbers come from? What is it...
Online integrator: http://www.wolframalpha.com/
\int \int (x,y,z) \times (x,y,z) \times (x,y,z)
\int_{L1} \int_{L2} (dl1,0,0) \times (dl2,0,0) \times (0,-1,0)
What would be correct syntax to evaluate this double integral?
I tried these, but they produce wrong result:

Hi, I'm trying to figure out how to use: http://www.wolframalpha.com/. I would like to be able to evaluate this function with different initial values and visualize results in some way, if possible:
d^2F = k/r^2 * i1*dl1 \times (i2*dl2 \times R)
Evaluate and visualize: k= 5, i1=i2= 1...
