how do i derivate f(x)=x^-2 using the limit definition? i keep ending up with 0/x^4

You dropped h from the denominator right above the crossed-out part.
The numerator resolves to -2xh-2h^2, and the denominator should be (x+h)^2*x^2*h. You eliminate h and substitute zero to get -2x/x^4, which is -2/x^3.
>>
You forgot an h in the denominator for the last two steps, try redoing it.

Can you guys give me any info about her? Even the same picture with a better quality or other pictures helps.
I've been searching her sauce for years, but I couldn't find anything.

I've been struggling in my Discrete math class and the midterm is coming up. He speaks with heavy heavy Chinese accent and rambles through the lecture. 70% of the class dropped but that isnt an option for me. Anyways, how would I go about solving this? If someone could point me in the right direction to teach myself it would be appreciated.

If you need to study for an exam, 4chan isn't enough. Talk to your TAs, ask the department head, or consult with your university student programs. Chances are your syllabus for the course even lists the university's student help program contact info.
You need a long term solution to your problem, not help with one question.

The short version is that any case can be described as a combination of (a)s and (b)s. This combination wouldn't be unique for that W(n) case; there would be different placements and set selections that fit.

I've found a solution but I have no idea where they got:
When n >2, W(n) = 2W(n-1) + 3W(n-2)
The rest is simple but Im just not understanding where the equation came from

Need someone to refer me to a free, safe, photo editing software for windows 10. Nothing fancy, just some croping for intentionally shitty meme making.
Thanks.

Mega legit, super great. I'm not the one who posted it here, but I was going to reply to recommend it. Strong community as well, so plenty of tutorials.

Does anyone know what type of spider this is? And what caliber gun do i need to use to kill it?

I'm not fully confident in naming that species, especially without a reference as to its size. Do you have an image of the web? Your location would also help a lot.
The smallest caliber of gun I've ever heard of is the .12 cal squirrel rifle, which would be overkill for this. Have you considered a fly swatter?
>>
>>279011
Did it bite you?
Can you now climb walls?
>>
>>279011
just looks like a typical "garden spider". there's a ton of varieties with varying color patterns but they're all pretty much harmless, even if the fuckers get pretty big. just smush him or better yet leave him alone
so i'm going to be building a gaming pc soon and I want to connect it to my hd tv. would it be better to use an HDMI cable for this application or would it be best to stick with VGA and 3.5mm audio cables?

HDMI is obviously better, and this is more a question for /adv/

my specs are as follows,
windows 7 X64
intel core i7 -4790k @4.00GHz.
X2 GTX 980 SLI
16 GB Ram
just a few days ago i was able to run any game at 60+ fps at max settings, and in 4k. But now on any game i frequently play at the lowest settings im not getting above 20 fps. is there anything that would suddenly cause that? none of my parts are much more than a year old, any help is appreciated.

check task manager to see whats using your resources

>temperature (dust, broken fan, etc.)
>bad ram
>auto updated drivers (newer version might suck)
>e-coin mining virus infection
it can be a multitude of things, its up to you to sort which is causing it
honestly i would start with temperature checking (cpu and gpu) and then revert back the graphic card drivers to the previous version (and disable the gayforce experience thingamabob)

I'm pretty sure it's Chinese, but I'm not an expert, I just watch a lot of Asian shit.
>>
>>278903
This is Chinese, and as far as I can tell, this doesn't form a sentence, they're just random chars. Here it is typed out so you can check for yourself: 細妍第感勇敢弹爆
What is the context?
>>
>>279050
>細妍第感勇敢弹爆
The last two characters are upside down and are simplified Chinese while the first few are traditional. Looks like something a white girl would get tattooed lol.
