To be honest, I’ve been feeling disinterested and unmotivated in pretty much every area of my life for the past year or so. Not very surprising as I spend a lot of time on schoolwork. For this reason, it’s hard for me to pin point exactly what it is that is making me hate school. All I know is...
I’ve finished two years of the math curriculum at my university here in Canada. I came here because I was excited about physics and mathematics in high school. Well, here I am now. I’ve been burned out since the end of first year, but for one reason or another, have continued onto finish second...
ah, thanks for clearly that up. That's kind of subtle, and I doubt I would've figured it out by myself..
i guess i forgot that one of the reasons why we speak of partial sums in the first place is that they are all bound..
:smile:
something funny's going on here, and I can't see what For a sequence {x_n} , where each term is non-negative
the series x_1 + x_2 + ... +x_n + ... converges
proof:
it will suffice to show that the sequence of partial sums {s_n} is bounded
where each s_i = x_1 + ... + x_i
when...
if I kept the minus sign where it was, which is what I did in my original solution, my integral would've been
ln(1+u)+ln(1-u)=ln(1-u^2)
StatusX told me to watch out for the negative sign in front of the u, so I factored it out, made sure that u was positive, and then integrated it, which gave...
hmm..
I've never run into anything like this before
so why does u having a minus sign in front of it pose a problem with what I did in my original solution?
(thanks for the help)
Homework Statement
Basically, I have to find
\int \frac{1}{cosx} dx
by multiplying the integrand by \frac{cosx}{cosx}
I go through and arrive at a solution, but when I differentiate it,
I get -tan(x)
something's clearly wrong, but I can't see what it is that I'm doing wrong...
eh, when you're in high school and at the top of your math classes and whatnot, it's easy to think that you're the next big thing
Once you get into university though, you find out that there are a lot of people just as smart and determined as you, school becomes a lot more challenging, and...
Probability is actually a second year course but I saw that it had a Calc II as a co-req, so I signed up for it thinking that I was safe. The calendar's description of the course:
The laws of probability, discrete and continuous random variables, expectation, central limit theorem.
As for...
cool, thanks
my schedule for next term looks like..
Linear Algebra I
Calculus II
CS 136- elementary algorithm design//data abstraction
Probability
Physics 122 - mechanics and waves II
those are uwaterloo courses right?
Just wondering.. generally, is it implicitly assumed that students in Pmath come from the advanced sections of the 100 and 200 math courses?
-first year student :-p
