How do you derive f(x) = (10x^2)/5 ??!?!??

[Anonymous No.6893831]

>>6893825
Just take x and multiply it by 10x and divide by 5

[Anonymous No.6893832]

By derivating it, nigga.

[Anonymous No.6893833]

>>6893825
It's already derived.

What the actual fuck? Are you retarded?

wait then how does integralation factor into this???!?!?
seriously guys i have my fourth calc exam tomorrow and i have a 67.6 in the class I NEED HELP NOW TO PASS

[Anonymous No.6893843]

>>6893825
f(x) = (10x^2)/5 = 2x^2
f'(x) = 4x
Also, your image represents an integral, not a derivative.
What was the point of this?

[Anonymous No.6893844]

>>6893843
WTF did you get that using the fundamental theorem of calculus thing or whatever? What exactly is that?

[Anonymous No.6893848]

f(x) = (10/5) * x^2
f'(x) = (10/5)(2) * x^(2-1) = 4 * x^1 = 4x

jesus fucking christ man wtf this is my second time retaking the class i cant do it over again if i fail then ill get dropped out of the engineering department

That makes two of us. :^)
I'm going to bed. Good luck with your exam.

>>6893844
On the offchance you're not a troll and you're actually brain damaged then that anon is doing it using a bunch of theorems that you prove. Using the formal definition of the derivative is a little more involved. Read your textbook, anon. You'll get a lot more out of your book than you will out of us. At least come back when you know precisely what to ask us.

im in a school in mexico city and spanish is my second language so its hard for me to understand what the textbook is telling me

thanks for the self-esteem boost, anon.

Do you need antiderivatives too or just derivatives?
Check your book, look at the practice problems, what kinds of equations do you need to know derivatives for?

Derivatives of some x^n are simple, it just becomes n * x^(n-1), so x^3 will become 3x^2, and if you take the derivative again it will become 6x (and if you do it again it becomes 6, then 0, then 0, then 0.. but this isn't important). You'll probably need to know a handful of derivatives too, like what is the derivative of log(x), or e^x or sin(x). Check your book nigger, you can use www.wolframalpha.com, just type your shitty equation in and it usually tells you the antiderivative and derivative somewhere. If you need more shit like how to derive derivatives and antiderivatives manually you're shit out of luck, that's pragmatic as fuck and I don't feel like typing for hours to explain how to derive two multiplied equations if you know the derivatives of each individual equation and splitting up antiderivatives and so on

I hope you do, if you can't do calculus I don't want you building shit.

[Anonymous No.6893928]

nobody takes a fucking derivative or whatever when their in the fucking field so get yiour facts straight before you talk shit faggot. destroyed.

Lmao. You won't take a derivative in engineering? Holy fuck balls you have no clue. I hope your internship with your fucking mechanic uncle goes well, this way in deep Utah some truck driving faggot won't get his car fixed well.

If you can't take a derivative and failed calc ONE, calc fucking OOOOONNNNNEEEE once already how the fuck do you think nasa is going to have any use for you?

Read your textbook you goddamn retard.

lol your argument techniques are laughable pleb. i bet the highest level of engineering youve dont is building fucking legos lolo0lolol

wtf faggot reply if your so tough ;)

[Anonymous No.6893987]

>>6893945
You're not going to make it in engineering if cal 1 is this much of an ordeal for you.

You might as well change to a business major, it seems like the only thing you are doing right is networking.

bro it's just f'(x) = 4x

you multiply the whole shebang by the power of the exponent, then take the exponent down by one power and

Well at least I'm trying and that's what employers look for most, not who can get the best integral or derivation or whatever so stfu you don't have practical knowledge

Everyone who applies for an intern position at nasa is trying you fucking retard.
The people who are going to get the position are those who are at the top. Those who have experience, who have fantastic grades, those who actually care enough to open their fucking text book and learn what you should've learned in the first few weeks of your high school calc class.
You will never make it. You will never be a part of nasa. You think that because you are "trying" then the job offers are gonna start flying in your face. Rofl have a good life nigga

I swear to god Sci is the easiest board to troll... Earlier there was that archangel infinity guy a baiting it out into 100+ thread and now this. Jesus Christ its like you guys are new to 4chan or what.
