Do robots know calculus?

>>34422871
Im not doing your homework lol

>>34422871
I can't even remember how to do algebra

>>34422871
I used to but I forgot it all in about a year

No I'm a fucking NEET what kind of a NEET knows calculus

>>34422871
I took ap calculus ab last year and got 86% and a 3 on the exam. Do your own homework

>>34422905
This. How the fuck do people remember this shit for the rest of their lives?

>>34422871
you just plug in 5 for t and it's unsolvable. Just put "No Solution" and you should get 100%

Try factoring the denominator in the second term and see if that gives you any ideas

>>34422871
OP, I failed geometry like 3 years in a row.
I only passed it in night school because it was dumbed down as fuck.

>>34422871
I used to and then forgot most of it.

Though I thought that limits where you're approaching dividing by zero needed to be specified as approaching from the positive side or the negative side

You're a fag if limits is hard for you. Don't even bother to think about taking calculus 2 you won't survive.

>>34422871
I plugged it into my calculator and got 2/5

I did know how to do this at one time but I forgot now

I think you would use l'hopital's rule for this, just differntiate the top and the bottom, right?

but that's not right, that would be 0 and mr. calculator says 2/5

so idk

The limit is zero.

t. hasn't taken calculus in 3 years

Robots are philosophical hermitists. Robots dont give a fuck about academics like math, science, or any of that shit. Robots are the free thinkers who paid the ultimate price of trading in their social status to being alone, sexlesd, and a life long of apathy. This is true happiness for them.

I sleep in my car, shower at the gym, and work a shitty job. Life is ok and I am free.

>>34422927
this sounds sexual

>>34422949
It's easier than that, just use algebra to simplify and get rid of the t - 5 term

>>34422939
just started calculus maine

>>34422927
4/t-5 - 40/(t-5)(t+5)

what now? i cant just cross out t-5, their diff fractions

>>34422952
philosophy is math though

Expand the quadratic so it's +/-5
Multiply the t-5 by t+5
Convert to single fraction
Substitute for t.

I forgot. Failed my degree.

>>34422972
Can you make it one fraction instead of two?

Errrr it = 2 right?

Sorry I run on windows vista

>>34422926
That isn't how limits work. You put in values approaching 5 from the left side for the left hand limit and from the right side for the right hand limit. If they are different then the limit is undefined.

fuck i failed calculus go ask /sci/

>>34422951
This is the answer.

>>34422981
maybe if i multiply the denominators on both fractions?

>>34422871
I'm actually taking Calc 3 and forgot how to compute limits. You never have to worry about computing limits in Calc 2 or 3, it's all just theory under the actual integration and series formulas.

>>34422871
For 5- it's - infinity
For 5+ it's who knows I'd need pen and paper

>>34422924
by not being a fucking brainlet lmao

>>34422871
It's Undefined.

>>34423125
Just the one on the left - you can get (t-5)(t+5) as a common denominator

>>34423182
More specifically you want to multiply the left fraction by (t+5)/(t+5), which is allowed since that's just another way to write 1.

>>34423193
lik this?

Holy shit, the limit is 2/5.
This is highschool level calculus

>>34422871
That whole thing when you simplify it will give you 4/t+5 and the limit is 2/5.

Fuck so many retards in this thread legit triggered my balls.

>>34422871
f(t) = 4(t-5)/(t+5)(t-5)

Which in the limit of t approaching 5 is just 4/(5+5) = 2/5

>>34423272
If you're still too dumb to figure it out it's:

(4t2-100-40t+200)/(t-5)(t-5)(t+5)

numerator is factorized to 4(t-5)2
denominator is (t-5)2(t+5)

>>34423307
what did you do with the 40?

>>34423332
He fucked up the process but got the right answer through sheer luck.
>>34423323
This is all of the answer.

>>34423332
Factor 4 out of the entire thing to get

1/(t - 5) - 10/(t^2 - 25)

Factor denominator of right fraction to get

1/(t - 5) - 10/(t - 5)(t + 5)

Multiply top and bottom of left fraction by (t + 5) to get

(t + 5)/(t - 5)(t + 5) - 10/(t - 5)(t + 5)

Now that we have a common denominator, subtract to get

(t + 5 - 10)/(t - 5)(t + 5)

which simplifies to

(t - 5)/(t - 5)(t + 5)

Finally remember the factor of 4 to get

4(t - 5)/(t - 5)(t + 5)

>>34423347
>He fucked up the process but got the right answer through sheer luck.

I just skipped some steps, see >>34423372

>>34423390
Why are we spoonfeeding him anyway this kid is probably in highschool and shouldn't even be on this board.

>>34423372
how come the denominators arent affected by factoring 4? where do you get (t+5) from to multiply left fraction?

>>34422923
meanwhile some kid took it during the summer and didn't waste his entire fucking year with calc 1 lmao

>>34423406
Yeah screw this kid, he should be doing his homework rather than browsing 4chan

Combine the two terms into one fraction. Notice that when we try to naively take the limit we get 0/0, so we can use L'Hospital's Rule.

4(t^2-25) - 40*(t-5)
--------------------
(t-5)(t^2-25)

Multiply everything out.

4t^2-100 - 40t - 80
--------------------
t^3-25t-5t^2+125

Apply L'Hospitals rule:

8t - 40
--------------------
3t^2-25-10t

We get 0/0 when we try to plug in t=5 again. Apply L'Hospital's again:

8
-------
6t - 10

Plug in t=5:

8
---------
6(5) - 10

Simplify:

f(t) as t->5 = 2/5

I think he's genuinely retarded. Apply to McDonald's kid you'll save yourself some time.

>>34422871
OP if you're still here I'm a math major and will help you.

I'm not going to give you the answer but this problem takes 2 steps: combining fractions with like denominators and using L'Hopital's rule.

>>34423495
Just fyi, you only have to multiply the first fraction by (t+5)/(t+5) to get a common denominator, and it saves you from having to use L'Hopital's rule twice.

>>34423497
how am i retarded if i dont know something??

I have until tmrw till its due btw

Thanks. I didn't even notice that the first denominator is a factor of the second.

it's limits they want you to show l'hopital's rule. whatever you did is just algebra.

>>34423906
Hopitals rule? In limits like this one? Are you kidding me? You literally need 2 operations to solve this.
What level is it? I hope high school, because if it's college I come there to study

Anon who wrote the exercise in the pic here.
It took me like 20 seconds to solve it, why do I have to use that rule? It simply makes me doing unnecessary operations

>>34423989
>>34423961
most likely his professor is looking for that rule if he taught it recently. but I don't know. it's a good rule to remember, just to get the habit. if you can't plug in the limit from the start I'd use l'hopital's like this guy
>>34423495

you guys both got the right answer though

>>34423989
It's just a manner of preference really. Not the guy you're responding to but when I look at that problem L'Hopital's rule immediately pops in my head so it's faster for me to do it that way, but if you see dividing out the (t-5) quicker then that's fine too.

We got the same answer because it's the right one, I just did less operations.
Anon didn't specify to use Hopitals rule if I read well, but I guess it's fine.
At least I proved the >>34423495 answer is right

>>34422871


Yeah I do, but it is admittedly basic shit every STEM student should master before going to the math fields which incorporate calculus and are actually usefull in a work scenario.
Calculating limits is useless 99% of the time.

If you only know basic recipe book math like calculus, discrete math, and the kind of computational linear algebra taught to dolts, and you are bragging, you are a legit tard.

>>34422871
f(x-h) - f(x)
-------------- its this I think double check it if you
(h) are taking limits its this formula
then you need to factor the t^2 into (t+5)(t-5)

>>34422871
forgot the quadratic part you need to make the denominators equal then take the limit

If t-->5-, lim is -infinite

My school never taught Calculus, but I'm learning math from the ground up again so in a month or two I'll get back to you on that.
