FlyerTalk Forums Expert How-Tos and Guides
Last edit by: tcook052
This new annual thread has been carved out of the previous thread in an effort to reduce the number of megathreads on the AC forum. For those interested previous versions are the original 2004 - 2014 thread , 2015 edition , and 2016 edition.

The original thread started by accident but quickly became a popular place to come and discuss off topic things such as hockey, new movies, or almost anything that wouldn't fit into existing AC forum threads. More Air Canada or Aeroplan topics such as flight feedback, in-flight services issues or mileage earning/redemption are all topics that should go into existing AC forum threads so others can benefit from this information. Topics about hotels or airlines and/or their loyalty programs or should be posted elsewhere on FT as should topics better suited to other forums such as Travel Products for questions about luggage or Travel Photography for discussion about cameras.

While the conversation is more relaxed as it would be in a lounge that doesn't mean however that the FT rules don't apply her as they definitely do so please refrain from controversial topics such as politics or religion, avoid profanities and treat other lounge patrons with the same respect you expect.

The proper mathematical term is called empty product.

My way of remembering it is:

1! = 1, and 1! = 1 * 0!,
=> 1 = 1 * 0!
=> 0! = 1

I was asking your thought process behind your conclusion 0! = 0

I was hoping you would have a more convincing argument
I remember I called math a "scam" when being presented with 0 to the power of 0 = 1 lol, not sure if it was junior high or high school.

Well, 0! != 0, so how can I come up with a "convincing" argument?

As for 0 to the power of 0, my first guess is undefined because:

0^0 = 0^(1 - 1) = 0^1 / 0^1 = 0/0 = undefined

But apparently the answer is 1

Edit: ok, i think you know what ^ means in this post

Explaining math without math, hmm, that's not math

Thinking about taking a spontaneous 24 hour trip on Dec 15th to Dec 16th, It has to be within reasonable range of YVR, where I can route back to it for the red eye home.

Thoughts, ideas? Thinking about San Jose, San Francisco, Seattle at the moment.

The goal is to depart from YVR, return back to YVR Saturday(16th) night to catch the red eye home.

I’m at YVR downtown right now leaving in the morning...

Rather last minute, but can anyone meet up for a bite to eat later this evening?

Edit: I’ll be at Metrotown for the next few hours but can meet around 8:30 or 9 or even later...

Just finished my midterm today so I might be interested. Though hoping for somewhere near Broadway / Burrard so it's not too long of a bus ride back to UBC.(but if not, downtown is still fine)

Anyone else?

If you’re near Burrard station, that works. I wouldn’t mind trying some Chinese food...

I've seen this a few times on CTV and TSN lately. Wonder if the public opinion of Boeing actually matters in the end in Canada. Think people will actually avoid certain flights/carriers because they will end up on a Boeing? Doubtful.

IMO, it has nothing to do with anyone avoiding flying on Boeing aircraft or avoiding airlines that fly them. Neither Boeing nor the flying public are under any illusion that the majority of fliers will choose to fly another airline to avoid a certain aircraft.

Public Relations campaigns have more than one target audience, just like advertising campaigns might.

There may be messages directed at the general public. There are also efforts directed at the stakeholders. In this case with the Boeing outreach campaign, it could be unions and/or any and all of the large number of companies who supply parts to Boeing and employ Canadians, and/or politicians who need to sooth their local constituents.

In my high school, in the rare question where things were not a sin/cos/tan of a convenient number in the unit circle, we were told to leave the answer as is -- e.g. sin(31) would be the correct answer and not whatever the calculated result is

My year was the first year using the new curriculum -- and those textbooks all had a section like "let's observe this function through a graphic calculator" .... which was pointless for us since, instead, we spent a huge chunk of the Gr12 calc class doing manual curve drawing instead (find the roots of f(x) to see where it crosses the X axis, take 1st and 2nd deriv, etc)

@Jumper Jack - seattle is closer (i.e. you spend more time in the city and less time in the plane) and more funner than sillycon valley
