@JasonBourne the only power I will lose is the ability to delete with more force. I'd rather have a pony.

user19161

@Mitch Ah! I don't want a pony. I can't ride a pony!

Johan Larsson

@JasonBourne you could also have used the account to work with the issues with obsession and addiction?

Mahnax

@JasonBourne I just got my flowing locks cut.

user19161

@JohanLarsson Well, I don't mean those words in a clinical sense there though, just ordinary layman sense. Not really something I need to work on in this case. But I figured there isn't much harm done and I am happier, so I decided.

user19161

@Mahnax Wow, any new pics to show us?

Johan Larsson

11:08 PM

@JasonBourne ok, qhwn you put it like that it makes sense and was probably a good decision

user19161

@JohanLarsson Well, it's up to the individual really. Some are fine with leaving the accounts there forever, and that is fine too. Speaking of which I do have some issues to work on, but this is not the case!

Johan Larsson

will all your answers go away?

Mahnax

@JasonBourne Not at present, no.

@JohanLarsson Ole hyvä.

user19161

@JohanLarsson No, all the posts remain! Which is why I chose deletion.

Johan Larsson

@Mahnax kitos (I think)

Mahnax

11:11 PM

@JohanLarsson kiitos*

Close, though.

Johan Larsson

ah, did not want to cheat, was pretty syre

Mahnax

> The film was shown in Swedish cinemas for nearly 11 years – between early 1976 and winter of 1986/1987 – which is still a record. When Forman learned this, he said, "I'm absolutely thrilled by that... It's wonderful."

(One Flew Over the Cuckoo's Nest)

Johan Larsson

funny thing, in the north of Sweden old people speak Finnish, on the other side of the border I think it is common that the Finns speak Swedish

Mahnax

@Johan, can you confirm or deny this claim?

@JohanLarsson Swedish is one of the two national languages in Finland, hehe.

Almost everyone speaks it.

Johan Larsson

@Mahnax I've heard it but would have to google it

Mahnax

11:13 PM

Hmm, okay.

user19161

@mah How was the test?

Mahnax

@JasonBourne Easy enough.

user19161

@Mahnax OK. Have you done trigonometric functions yet?

Johan Larsson

@Mahnax Two versions of Finnish are minority languages in Sweden miänkieli and Sámi at least I think Sámi is similar to Finnish

Mahnax

@JasonBourne Like sinθ/cosθ=tanθ?

Johan Larsson

11:17 PM

@Mahnax Could google confirm it at least

user19161

@Mahnax Yeah, have you done sin cos tan cosec sec cot already?

Mahnax

@JasonBourne Yes.

user19161

@Mahnax Ah, I would like to give you a quiz question. Ready?

Mahnax

@JasonBourne sighs OK…

Hehe, yeah. I'm ready!

user19161

@Mahnax What is the difference between 1/tan x and cot x? Or is there no difference at all?

Mahnax

11:20 PM

@JasonBourne Umm, they are the same, as far as I know.

user19161

@Mahnax Hmm OK. Well, if we define cot x as cos x/sin x, this is not the same as 1/tan x.

Mahnax

@JasonBourne But we don't. We define cotangent as the reciprocal of tangent, i.e. 1/tanθ.

user19161

@Mahnax Ah, the more usual definition is cos x/sin x actually. So do you see the difference between cos x/sin x and 1/tan x ?

Mahnax

@JasonBourne Nope.

user19161

@Mahnax At odd multiples of 90 degrees, the former is 0 but the latter is undefined! QED.

Mahnax

11:24 PM

@JasonBourne You're right, of course.

user19161

@Mahnax So now you see the advantage in defining it as cos x/sin x? The graph has less holes!

Mahnax

@JasonBourne Yep.

user19161

@Mahnax Not many high school teachers will point out to you this subtle difference.

Mahnax

@JasonBourne Many tired Mahnaxes will not, at first, notice this subtle difference.

May I have another question?

user19161

@Mahnax This also gives an example of how in math, we can give slightly different definitions of the same term which are not equivalent.

user19161

11:29 PM

@Mahnax OK, another trick question. Have you done things like sine rule and cosine rule for finding lengths and angles in a triangle?

Mahnax

@JasonBourne Yeah.

Is this going to be an ambiguous case question?

user19161

@Mahnax A student was asked to find the angles of a triangle using the sine rule up to one decimal place. After finding the angles, he added them up and found they were greater than 180 degrees! What could have happened?

Mahnax

Is this going to be an ambiguous case question?

user19161

@Mahnax Oh well, the question is the question. Ambiguity is not well-defined!

Mahnax

@JasonBourne Umm, there is the thing called the ambiguous case, which can occur if you are given a side, angle, side, and the angle given is the smallest one.

I don't know if that is what you are getting at or not though.

user19161

11:34 PM

@Mahnax Oh no, nothing to do with that!

Mahnax

@JasonBourne Oh, OK.

Let me think about it then.

user19161

These are my favourite two trick questions for school kids.

Mahnax

I don't know. He rounded incorrectly? I am way too tired for trick questions.

Hmm, wait.

user19161

@Mahnax No, the answer is this. He rounded correctly, and the sum exceeded 180 because of rounding up! For example, maybe the angles were 60, 60.45... and 59.55... After rounding you get 60, 60.5 and 59.6 which add to 180.1 hahaha

Mahnax

@JasonBourne swift kick

user19161

11:44 PM

@Mahnax Now you can tell your friends these two trick questions!

Mahnax

@JasonBourne Why would he round them before he added them though? That is silly.

user19161

@Mahnax Why would he even add them before that? They always add to 180 exactly anyway!

Mahnax

@JasonBourne Maybe he was checking to see if his answers were right.
