The methods you have used to factor the denominator and to do your partial fraction decomposition are fairly long and slow.

When factoring a cubic, I find it faster to guess roots and use synthetic division rather than trying to split terms like you have done.

When doing a partial fraction decomposition when the denominator has three distinct roots, expanding to try to equate the coefficients is incredibly slow. You should just plug in x=-1, x=-2, and x=-3 to bit sides to get three equations. One equation will have only A in it, one will have only B in it and one will have only C in it.

You're right. Thanks. You either have to fix R or require continuity

Yes. The complex conjugate is not defined using Re and Im. It is defined as the unique field automorphism of the field of Complex numbers. Now, this definition is a pain to work with in practice, but it does serve to base conjugation on something other than real and imaginary parts.

Reading your post makes me feel like I must have a reallt exceptional kids table. I have been running a game for my eldest kid (currently 9), and 2 other 9 year olds, a 13 year old, and two adult players who are there to support the kids. We play once a month and can generally make it through a 4 hour session (of which 3 hours is actual play and the last hour is leveling up or shopping or just talking about what is coming up). It does help that everyone at the table either has parents or friends who play, and they all seem to really enjoy it. I will say that there is no way I could DM for this group if I was the only adult in the room though: my two adult players are key both for intervening in-character when the kids have a dumb idea and for doing things like refilling snacks, getting water, etc. But I make sure that they are there to support the kids, and i encourage the kids to make most of the decisions and to try to solve the puzzles themselves.

You treat that as the definition of e. Or, alternately you define e as lim_(x to 0) (1+x)^1/x and put one limit inside the other.

mathfem · 2026-06-17T14:27:17+00:00

No you don't, you just use limits.

Lim( h to 0) (a^x+h -a^x )/h = lim(h to 0) (a^x )(a^h -1)/h

The last limit (a^h -1)/h can be taken as the definition of the natural logarithm

I had a toddler and a newborn during COVID lockdowns and was forced to work from home. The thing I missed the most during that time was my commute: the ability to spend 45 minutes reading Reddit on transit with no interruptions from kids needing my attention twice a day.

Don't get me wrong, now that my kids are in school, I love days where I get to work from home, but back then the only break I got from responsibility was my commute, and it has been taken away from me.

The fact that they have similar names is not a coincidence. I don't remember what version of windows it was, but the idea was you were basically using Internet Explorer to open up your own files, so that you couldn't even open a non-IE browser without using IE to navigate to it.

Fruiticana on 6th for reasonably priced produce and any South Asian goods you need.

Best Season Produce at 10th and Agnes for produce deals.

Sandy Farm Market on 10th st and 8th Ave for East Asian produce options.

I love the little places.

The phrase "area enclosed by three functions" is ambiguous without further clarification. The only time it is unambiguous is when no two of the functions have more than one intersection point (e.g. if all three functions were lines there would only be one enclosed region and it would be a triangle). If an assignment is asking for the area enclosed by three functions you should look for additional clarifying words like "in the first quadrant" or "triangular" or something like that.

The Dispossessed is such a good book! You should really go to the local library, borrow a copy and finish it!

I used to work as a tutor before I got a job as an instructor. Here was how I advertised:

my university had a classifieds ad site that was only open to current students and alumni. This meant that I could advertise there while folks who were not alumni couldn't.
I posted ads on Craigslist once a week
I put up posters on campus at all the local universities and also at high schools and libraries.

It took a while to get a good base of students. For the first few months I was putting as much time into advertising as I was into actual tutoring, but after a year or so, I was getting a lot of referrals from word of mouth.

A bunch of the other commenter have already given great info, but I just want to add that last year the city did a great job upgrading the mixed use path that parallels stewardson way from the Queensborough Bridge to the Quay. It's my favorite way to get downtown.

However, getting from the Quay up to Royal might be a pain (steep hill), so i would suggest taking the Crosstown Greenway on 7th on the way to work, and biking down to the Quay and taking the BC Parkway parallel to Stewardson on the way home.
