I am not a cat person, but Chi is not a cat. He is a kitten. There is a difference.
There has been a bit of buzz about this series (including this attempt to somehow treat the series seriously which is ultimately doomed to failure because, well, this is Chi’s Sweet Home we’re talking about here), and as I first heard of the series on IRC on April 1, there was a tad bit of trepidation on it, as I was deathly afraid that somehow the innocuous-sounding Chi’s Sweet Home would actually turn out to be a blood-soaked murderous cat rampaging through Tokyo and totally macking on Godzilla’s turf.
That is not what Chi’s Sweet Home is.
This is what Chi’s Sweet Home is: cute^2. No, no, that’s not nearly math nerd enough. How about d/dcute∫7cute^2+5cute dcute? (EDIT: see below for information on why I am completely incompetent at mathematics, because I totally am and this is why I write instead of trying to find the Riemann sum of a set of discrete integers) I don’t even know if that can actually be easily integrated, but I don’t care because integrals are the most inherently hilarious mathematical functions, especially when applied to things that cannot be integrated, such as the abstract concept of cute (or, for the loyal xkcd reader, i.e. someone other than me, the infamous integral of love strip). This humor value is, of course, derived (pun may or may not be intended, I am as unclear on this matter as you are) from how difficult the things are, but that’s why I’m getting a history degree and not a physics degree.
I digress.
Chi’s Sweet Home is the perfect bite-sized chunk of eponymous sweetness and cute. It lasts a whopping three minutes, so it’s not like you need to sink in a massive amount of time, and, as long as you think kittens are the cutest thing since ever, you will be aptly rewarded. Fans of the cat episodes of Sketchbook ~full color’s~ have probably already watched this series and have been feeling quite happy as a result.
Now we just need a sequel series for a puppy. That would be even more incredible. But that’s just me.
Anime wa Bakuhatsu da! 
“∫7cute^2+5cute” is incompletely written because you didn’t have “dcute” (I assume you meant that) at the end.
Anyway, “d/dcute∫7cute^2+5cute dcute” is the derivative of an integral, so the two calculus functions negate each other, and you’re left with the original “7cute^2+5cute”. Not complex at all. ^_^
Oh, and yes, I do like the cats.
Do you understand now why I refuse to take another mathematics course ever again?
THIS IS WHY. THIS IS WHY.
Thank you for correcting me, though. I last went through Calculus II approximately 4 years ago, and, while I could probably explain to you the useful properties of integrals, this very sort of incompetence is why I scraped by with a C and vowed never to take another math class again. Math nerd jokes still amuse me, though, but obviously I shouldn’t try to actually make them.
When I took Calculus, I was find with differentials, but integrals killed me.
Chi’s Sweeet Home is fun to watch, though I’m not sure I’ll fall in love with it. Chi’s face and voice prevents me from doing that. :P
