Bucket's Questions

[enwiabe]

children, children, no more of this public bickering. Take it to a private channel. Don't make me reprimand you guys

[bucket]

moving back onto the topic; how do I deal with this question :p

thanks

You've deleted coblin's posts before on a maths board. It is disgusting behaviour.


Why the hell would I care what you do to your own posts? When you infringe upon the rights of others is when I get angry.

I had chocolate ice cream last friday. You should condemn me because there are still kids in Africa in poverty.

OT:

That's the fundamental difference between the idea of human "rights" and what is a sustainable set of rights. When people believe that kids in Africa have some inherent "right" to food, although it is well-intentioned, it implies they have the right to coerce others to attain that food. On the other hand, libertarians believe that the set of rights that humans have are based on what they cannot do - that is, they cannot infringe on the rights of others. When you produce rights based on what they can do, it means they have some command over resources that they do not own, and it is not viable in a world with scarce and finite resources.

It's the contest between positive rights and negative rights.

That said, however, when you post on a private forum, you don't have the right to have your post permenantly etched into the server. It is to the discretion of the owner (and whoever the owner delegates to moderate).


Don't be silly about the rationalist thing. I've made a few posts explaining the flexibility of rationalism, and I've explained to you on IRC how rational behaviour encompasses any kind of value-input (including yours!). The only reason why you love quipping "rationalist, rationalist!" is because you used to be able to fool people into thinking that Brendan and I have a heart of stone. If you actually read our posts, you would see we acknowledge that other opinions are well-intentioned but we show how they do not actually get them to that point.

Oh sorry, am I in the wrong place?

[bucket]

Hmm, does anybody have any questions which are similar to "consider equation f(x). Find the tangent which touches this curve and passes through the origin"?
I need some practice with these questions...I've only done like 3 in my whole life >.<.

[bec]

Yup, I was just doing one then!

Let . Find the equation of the tangent to f(x) that passes through the origin.

neap 2006? :p
lol thanks anyway bec

haha i tried

"State the maximal domain for "
In a previous part of this question I sketched ...do I use that graph to help me or do I work it out algebraically?

[nerd]

Well, all you need to do is look at the graph and see all the points where y is negative and NOT count those in the domain.

Remember that you can't take the square root of a negative number, but all other values are ok!

oh thanks =]

[shinny]

And don't forget to not include the asymptote, but to include the x-intercepts.

[Collin Li]

You've got two main conditions that need to be satisfied (the intersection of these two):

1)

2)

The second one is a bit more complicated:

Either (i) or (ii) are acceptable domains (i.e: the union of these domains constitute the 2nd condition)

i) if , then , hence:

ii) if , then , hence:

So, the maximal domain is the intersection of:

1) , and

2) the union of and

So you should get all real values excluding the region
