Anyway have you got yours yet? Are you planning to go to U of C?

Yea, hopefully I can get into U of C

You're retaking the whole course for 2%? That seems like alot of work for 2%...

Waterloo is a great school

The last 2 profs I have had from Waterloo don't really lend a lot of support to that statement.

Actually, to be honest they were not bad or incompetent but their teaching styles were so different from anything else at the UofC and so similar to each other that I just assume it is an institutional difference more than anything else. One was pretty new as well, so that may have played a big role in it. I am pretty sure there are others on this forum who are in my networking class this semester who would probably agree.

4. Solve sin2y=cos4y for y, where 0<y<360. Hint (cos4y=cos(2y+2y))

Also just wondering guys, this question was worth a lot and I just want to make sure if I am on the right track.

In Saskatchewan, the sun rises at 09:17 on December 21 and at 04:35 on June 22. Because there is no daylight savings time in Saskatchewan, the time the sun rises on any other day can be predicted from a sinusodial graph with a period of 365 days.

Write a sinusoidal equation that realtes the time the Sun rises to the day of the year.

I got
y=2.35cos(2pi/365)(x-173)+6.933

is this the right way?

Some other questions (I need to hand in the entire course haha)
1.To play a game, a die is rolled to see who plays first. Four players are goig to play the game. What is the probability that atleast two people roll the same number? Express your answer to the nearesr tenth of a percent.

2.Zayra wrote a computer program that randomely printed the letters of the words given to it. The program is given the word REPEAT. What is the probability that it prints out the letters so they spell the word Repeat? Round your answer to 4 decimal places.
---I went 6!/2! =360 ways in total...and then I am not sure if there is only one way I use to spell the word or two ways considering there are two "E"'s. Should i go 1/360 or 2/360?

3.There are 12 feathered shuttlecocks and 9 plastic ones in a bag. If two shuttles are pulled from the bag without replacement, determine the probability:
a)1 plastic and then 1 feathered
---would we go (12P1 X9P1)/21P2?

b)1 plastic and 1 feathered
---would I go (12C1 X 9C1)/21C2

C)Atleast 1 plastic
----would I go ((12C1 X 9C1) + (12C0 X 9C2))/21C2


After, this I am done everything..


I accidentally edited my other post with this.

I had a prof who came from Waterloo engineering who said the same thing. Lots of good students and they do lots of research, but if you are an undergrad, research isn't such a big deal. The main critisism I hear of engineering students at Waterloo is that because the quality of students is so high, students are too proud and everyone just ends up trying to figure out everything on their own.

I never went to Waterloo though, so I have no personal comment myself.

Isn't McGill suppose to be Canada's best university

[Phanuthier]

Quite honestly, your university experience is what you make it out to be. As far as sci/engg goes, every school teaches you the same thing. What I noticed since going to graduate school was the only difference between students was, those who came from better schools were able to work independently, learn on their own and take initiative; and those who came from crappier schools tended to rely on other people to teach them (i.e. my lab partner who asks me things that you can easily google up, but says its faster for him to ask me - even if its for me to google it up, learn it, then teach him)

Haha, there are some bad schools out there

I think my 3 years at Bishop Carroll definitely helped me to prepare for university, since it was an independent learning school, I had to learn out of a textbook. Oh well, we'll see how it goes next year. I'll still be around CP daily (hopefully), get my daily dose of Flames hockey.

I dunno, I went to Sir Winston Churchill. I know my best friend went to some high school in Olds were only 2 of his graduating class made it to university, and has a 3.9 GPA in electrical engineering. I also know my ex-girlfriend came from a Edmonton school that had 3/?? students make it into university, and she is doing her masters in electrical engineering as well.

Hey man, just wondering, do you think you can help me on my last couple of questions (2 are actual questions), the others I am just wondering if I did it right. Your help would be greatly appreciated.

You already took out repetition with 2!, so its 1/360.

o ok thanks

Sounds like you are ready for Waterloo then

Are you doing mechatronics? My cousin is doing mechatronics right now at Waterloo. A word of advice, look at what your future prospects are and make sure they align with where your degree takes you. My cousin (in mechatronics) I think - last time I talked to him - somewhat regrets his career path due to the job prospects of what he can do with his degree.

So what are you studying and where? Just wondering, not sure if I missed this info though haha

Explanation: [cot(Θ)] = [1/tan(Θ)]. tan(Θ) cannot be undefined or zero. At [(pi/2)+n(pi)] (90 degrees + n[180degrees]) where n is any integer, tan(Θ) is undefined. At n(pi) (n[180degrees]), tan(Θ) is zero. Therefore, cot(Θ) at those points would be (1/0) which is undefined.

Tan can be infinity. 1/(infinity) is zero, so the equation is still valid.

I'm planning to do Software Engineering, so I'm assuming that the career path for it isn't too limited. I'm thinking about finishing my degree, 5 years with coop program, then working for a year or two and go into a law school. I'm not too sure about how that works, but if you have some words of advice about it, I'd love to hear it. (I mean law schools)

I'm doing my masters in integrated circuit design. Basically the math you are doing, I make circuits to do that. Except I try and do it really really fast. And I get to debug all the errors using what you are asking here (statistics of white noise in circuits... mean... deviation... if I'm lucky and the noise is Gaussian distributed)

The 2 questions... if you post it, I can give you recommendations and help you along the way. I don't mind taking a look to see if you are on the right path, but I just don't believe in giving someone an answer; I'd rather they propose what their solution is, and if you are wrong, then I tell you where you are wrong and which direction you need to go.

so thats not the right answer?
