say somebody hasn't taken maths in a few years and they have 6 weeks to study until they start calc 1. what are the essentials that they should review?
buimo
>>7941059
>6 weeks to study
>calc 1
You litearlly have to do nothing.
>>7941102
I wanna be prepared anonymoose
c'mon anons, what is 3 things that you absolutely have to be comfortable with
>>7941123
Your body, your brain and your heart.
>>7941125
you brought a tear to my eye anony
>>7941059
How long have you known that you're going to study calc 1?
lol just understand factoring and graphs of functions or some shit, don't worry anon
>>7941109
If you suck at factoring or trigonometry, practice that shit for all your 6 weeks time. Thank me later once you're in Calc II and have to do trig sub.
And for limits, if you need to factor the equation because it'll result in indeterminate form, just use L'Hôpital's rule instead because it's far faster, easier, and gets you the same results.
L'Hôpital's rule is basically: [math]\lim_{x \rightarrow FUCKERY} \frac{f(x)}{g(x)} = \frac{f'(x)}{g'(x)}[/math]
The primes represent the derivative. If you want to differentiate something, all you'll ever need is power rule and chain rule really. Once you get into Calc II or let's say you need to prove the derivative of some trig function, then you may want to learn about the quotient rule.
Power rule of differentation: [math]\frac{d}{dx} ax^n = (n)ax^{n-1}[/math]
Chain rule: [math]\frac{dy}{dx} = \frac{dy}{du} \cdot \frac{du}{dx}[/math]
Quotient rule: [math]\frac{d}{dx} \frac{a}{b} = \frac{(b)(a') - (a)(b')}{b^2}[/math]
And lastly, do not let negative fractional exponents fuck your brain up. Good luck.
>>7941130
How to work with fractions, trigonometric identities and how to write roots as exponents(plus manipulate exponents).
Other that that... doing cal 1 is pretty good practice for cal 1
>>7941131
69 days
>>7941145
So why have you only just started thinking about it now?
>>7941143
Ya I'm fine on all that sqrt(x)=x^.5 | 69th root of x = x^.0145
>>7941142
don't know any of that senpai, what is all this called so I can study it?
>>7941149
idk
>>7941059
Go to khanacademy.com and watch all the videos on trigonometry.
Do practice problems on khan (if they're available), or from another website or a textbook somewhere.
This is literal cancer.
9gag tier stop posting memes.
>>7941163
sir these are /pol/ maymays
>>7941059
If you're done posting euphoric red pilled MS paint pictures, you have the wonderful option of khan academy actually covering your babby tier math. Just watch all the videos at 1.5 speed and do all the practice.
Dude it took me 5 days to learn calc 1 ez pz m8
>>7941172
>>7941170
thanks guise
>>7941157
At this point I know you're just trolling. But what I just showed you is what you should expect to be learning and doing in your first semester of Calc I. If you've taken precalc before, you should be familiar with limits already.
The other 3 rules I showed you which were the power rule, chain rule, and quotient rule are the rules that are most commonly used in differentation. I will show examples.
Quotient rule [eqn]
\begin{aligned}
\frac{d}{dx} \sec x &= \frac{d}{dx} \frac{1}{ \cos x } \\
&= \frac{ \cos x(1)' - (1) \cos' x }{ \cos^2 x} \\
&= \frac{1 - \sin x}{ \cos^2 x } \\
&= \frac{1}{ \cos x} \cdot \frac{ \sin x }{ \cos x } \\
&= \sec x \tan x
\end{aligned}
[/eqn]
Power rule and chain rule [eqn]
\begin{aligned}
u = \sqrt{5x+3} \\
\frac{d}{dx} \sqrt{5x+3} &= \frac{d}{du} \sqrt{u} \frac{d}{dx} 5x+3 \\
&= \frac{1}{2} u^{ - \frac{1}{2} } \cdot 5 \\
&= \frac{1}{2 \sqrt{u} } \cdot 5 \\
&= \frac{5}{2 \sqrt{u} } \\
&= \frac{5}{2 \sqrt{5x+3} }
\end{aligned}
[/eqn]
L'Hôpital's rule [eqn]
\begin{aligned}
\lim_{x \rightarrow 3} \frac{t^3 - 9}{t - 3} &= \lim_{x \rightarrow 3} \frac{3x^2}{1} \\
&= \frac{3(3)^2}{1} \\
&= 27
\end{aligned}
[/eqn]
I hope this renders...(it rendered in the preview)
>>7941183
Why stop there. You should also be teaching him how integrals work as well.
>>7941183
I didn't ask to be taught calc I asked what I should do to prepare for calc. Isn't all the stuff you posted besides limits part of calc 1
>>7941187
He just wants a head-start at Calc I. Otherwise, I would've also shown him integrals. You know what? I'll show an integral, fuck it, I have no life anyway. [eqn]
\begin{aligned}
u = \sqrt{5x+3} \; \; du = 5dx \; \; dx = \frac{1}{5}du \\
\int \frac{5}{2 \sqrt{5x+3} } \; dx &= \frac{5}{2} \int \sqrt{u} \; \frac{1}{5} du \\
&= \frac{5}{2} \frac{1}{5} \int \sqrt{u} \; du \\
&= \frac{1}{2} \int u^{-2} \; du \\
&= \frac{1}{2} \frac{u^{ \frac{1}{2} } }{ \frac{1}{2} } \\
&= u^{ \frac{1}{2} } \\
&= \sqrt{u} \\
&= \sqrt{5x+3} + C
\end{aligned}
[/eqn]
>>7941200
PLS JUST PRETEND I DID NOT PUT THE FUCKING RADICAL FROM [math]5x+3[/math] IN [math]u[/math]. I'm not being paid for this so....
>>7941197
This shit will prepare you for Calc. What else do you want?
If you want to prepare for calc I without actually doing any calc I. Then just practice factoring and trig and literally nothing else. It¨s not that hard.
>>7941059
Everyone else is just wasting your time and probably making you anxious. Ignore these clowns.
Either use khanacademy, which is a free website with math videos, or, even better, do the following.
Google "best precalc textbook for self study"
Buy a used version of the result.
Read the book and do odd problems at the end of each chapter.
Do this for about 10 hours each week (2 hours per work day) for the remaining six weeks you have left
If you do this, you'll be more than prepared for calculus 1.
>>7941209
I just wanted to know the essentials, I'm just skimming through a couple free online textbooks and doing a few practice problems from each section
here are the books:
http://stitz-zeager.com/szca07042013.pdf
http://mecmath.net/trig/trigbook.pdf
http://www.math.washington.edu/~colling/HSMath120/TB201112.pdf
Would you say this is sufficient?
>>7941220
shit forgot the meme
>>7941223
that's probably the only good meme in the bunch
>>7941220
This is more than enough really. All you need is http://mecmath.net/trig/trigbook.pdf because it covers all the trig you'll ever deal with in Calc I - III. You should familiarize yourself with the sigma notation, not how to do it all but at least just know enough about it so you know what's going on when you see it later on. Ex: [math]\sum_{n=1}^{100} n = \frac{100(100+1)}{2} = 5050[/math]
What's going on there is basically this, you're doing a summation of [math]n[/math] from [math]1 \rightarrow 100[/math]. The result yielded is the same result as [math]1+2+3 \; . \;. \; . + \; 99+100 = 5050[/math]
>>7941233
I forgot my meme, too.
>>7941233
Ya I understand basic sigma notation. basically adding up all the numbers in a given series. isn't the upper case pi the same except it is multiplication
>>7941253
Yup. Uppercase pi is just the product of a series. [math]\Pi_{n=1}^3 = 1 \cdot 2 \cdot 3 = 6[/math] and shit.
>>7941059
literally only multiplication and special angles. Maybe a couple trig identities. The rest is all new.
how did this thread turn to such shitpostering so rapidly

This entire website is anime
Currently taking Calc 1. If I had the time you had (I did except I blew it), I would have focused on memorizing trig identites, solving trig equations, memorizing lagrules, solving log euqations, simplifying algebraic expressions and rational functions
>>7941321
Pedophile microwaved-chinese cartoons are this site's foundation and I contributed more math advice on this thread than you.
>>7941386
Will brush up on logs.

I'm almost positive anybody above 9th grade can deal with those
>>7941142
why do you filthy american needs to call everything "rule"
do you at least understand those ?
from what i see in your post you don't seem to
>>7941396
>look mom I finally used the shit I learned on Khan Academy !!1!!
shut the fuck up you retarded weaboo, you pathetic show sure proved what a massive faggot you are
why do you make shuch a big deal of shit that OP will pick up in an hour if he has half a brain ?
