I am experiencing difficulty learning Trigonometry for the first time. I am currently working on graphing sin/cos/tan functions as well as inverse functions. Hit me with your best information and insults.
>>7890823
Lurking because I'm in calc III and I still don't fucking understand trig.
try it with tau
>>7890828
You give me hope. Even the tutors at my school teach trig with ridiculous apprehension.
Why can't we travel at the speed of light? How could mass reach infinity, when infinity isn't actually a number?
>>7890714
>How could mass reach infinity
It can't. Everytime we say something diverges to infinity in physics, we mean that we don't know what actually happens but it isn't good.
>>7890714
It can't.
The point is that the faster a massy object travels, the more energy it takes to accelerate it. This energy grows exponentially the nearer you are to c. Taking the limit, then, we say infinite energy (part of which will transfer as mass as well) is required to reach c with a massy object.
>>7890714
Gravity has the same speed as light, so the only logical and theoretical way to travel near the speed of light is to ride on a gravitational wave
Senior math major here, I need a topic for what to write my final paper on.
Originally I wanted to find something about the Fibonacci sequence I could write about, just because it interests me. But specifically I don't know what about it I can write 15 pages worth.
what were some pitfalls you've made trying to write a math paper?
first you research something and produce some results
then you get down to writing the paper
>>7890284
Write it about how you're going to wind up teaching high schoolers how to do algebra.
>>7890290
maybe as a sub, that would suck. I'd like to pursue the actuarial field.
What does the sixth dimensional equivalent of a Mobius strip look like /sci/?
I need this to complete my loop.
>>7890192
Like a six dimensional mobius strip
>>7890214
Yeah yeah, I get the whole "paradox queen" thing and everything, but something about taking six of my words and jumbling them about seems mighty similar to circular reasoning to me.
(Technically five words and a subset of the fourth, really.)
Imagine 4 4D connected Klein bottles.
Is he the savior of Mathematics?
Define savior
he's a hack

wtf is that
is that even english
how accurate is the science in the martian?
Better than almost any other sci fi. A lot of it is a bit far-fetched (which is kind of the point), but nothing is outright wrong.
Better than average for Hollywood (I assume this is mostly owed to the novel's own accuracy). Still a few inaccuracies, though. The plastic-and-duct-tape hab repair job was pretty laughable, especially when the fucking wind was enough to cause it to invert.
Probably the most glaring inaccuracy was the one that pretty much ruins the entire premise of the movie - that the team was able to just pick up and head straight home without him. In reality, they could get to the Hermes in Mars orbit, but then they would still be stuck there until the next return transfer window...

this is what I've heard
perhaps some issues with perchlorates in the soil?
it didn't make me cringe unlike that shitfest that was interstellar
check out the article guys, what do you think this spells for our future?

Nothing much really
I know we don't normally help eachother out, but please, please, please take a little trip over to /x/ and help explain gravity to this Flat-Earther. They post a new thread every fucking day because they don't understand how Earth works.

i would but im chem
if you got any chem questions i can help you senpai
>>7888856
I can give a little help. First one is just regulations, google ETOPS. You don't wanna be caught trying to make an emergency landing 4 hours away from any airport.
Second and third, if the atmosphere didn't rotate with the Earth, we'd be blasted constant supersonic wind
>>7888881
This.
Explain to him that "at rest" all objects on Earth, including planes and the atmosphere, are moving with the Earth. That is the default state.
>sin 2x + 1
Is this either:
>sin(2x) + 1
or
>sin(2x + 1)
>>7888840
it's sin(2)*x+1
>>7888840
Could be either. Check your book for answer
>>7888840
s*i*n*2*x + 1
/sci/entists like to claim that their IQs are over well 130. Then a simple puzzle like this should be easy for you, right?
>>7888804
>/sci/entists like to claim that their IQs are over well 130
It's only the 15 year olds and stormfags who boast about "muh iq test results I got from a website by googling 'real iq test'". It's impossible for anyone with an IQ well over 130 to actually believe that their results they got that the websites scripts wants them to shareon facebook is not bloated crap.

this. i always scored well above 130 on online tests. my real iq is below 120.
What will the world be like in 20,000 years?
Basically shit.
For us anyways.
Thanks to technology changes like google glass and such the humans left may have more specialised senses caused by the changes in how we use our bodys?

What is the laziest job in STEM and how to get it?
How do you expect to succeed at anything like that?
Grow up, stop watching cartoons for pedophiles, and actually work.
>>7887604
Look not all of us want to waste our only life laboring away and having 1 week vacations to Cancun every year to "relax". So my goal is to not have to work. Thus by working I'm not really succeeding.
>>7887610
You don't have to work when you're dead.
Since registration just happened at my Uni
Post the most bullshit course your Uni offers.
Mine: Graduate level course titled - Social Justice Pedagogy
Caribbean Spirituality, under Black Studies.
I actually want to take this

How does anything stay in orbit for millions of years with all the stuff (asteroids and such) hitting it and slowing its movement down.
>>7887525
That stuff is very small
>>7887539
Like OPs dick
>>7887525
It does deter the orbit a bit but not too significantly.
It's true that minor fluctuations accumulate and the effects grow exponentially.
Any chemistry majors here?
>>7887294
Almost with a BSC in Chemistry; however, switching majors to Chem. Engineering.
Hello
Yeah, I'm specializing in medicinal chemistry, second year.
