Oops , sorry for that , I edited it.Hi Zaid,
Both of your links refer to the same page.![]()
What's wrong with that?
Good point. Not to hijack the thread but can you quickly tell me how you would tell Wolfram x is real?You have to somehow tell Wolfram Alpha that $x$ is a real variable. Otherwise it will assume that $x$ is a complex variable. And if $x$ is a complex variable, $\displaystyle \int \frac{1}{x} \ dz = \log(x) + C$ is a true statement.
I often come up with a whole lot of mistakes on that particular site.
Look at the leftmost edge of the page and you'll see a tool to send message to the editorial board. Quote the line you feel is incorrect, then send them that.
Which mistake?Yeah, right. An awful lot of mistakes. I once tried that send message and sent the error and correction but no one looked at it, and remains incorrect today as well, and so I think its useless. In fact, I think Wikipedia is less error-prone than Mathworld.
One that I found recently: Semiperimeter -- from Wolfram MathWorldWhich mistake?
So where is the mistake in that article?One that I found recently: Semiperimeter -- from Wolfram MathWorld
"and Brahmagupta's formula for the area of a quadrilateral:"So where is the mistake in that article?
Erm...it is."and Brahmagupta's formula for the area of a quadrilateral:"
Is that formula after that Brahmagupta's!
Yep, sorry, the wikipedia article I linked to also states that it is Bretschneider's formula.
At least, more than wikipedia in any case.IlikeSerena said:Hmm, so the math is perfectly correct and as such MathWorld is reliable.
I'll bite.At least, more than wikipedia in any case.
Somehow, I knew you'd say that. There have been many changes in wiki since I saw them, so I will show you only the ones I can find.Where is the mistake in wikipedia?
No, the formula named is wrong, which is problematic.Hmm, so the math is perfectly correct and as such MathWorld is reliable.
The problem is that the credits given are not correct in that article.
Just now, I have sent a contribution to MathWorld with the suggestion to correct this.
We'll see.
But you can correct errors in Wiki with no prob. The MathWorld team however never listens to any suggestion and the mistake remain mistakes.At least, more than wikipedia in any case.
