Take [math]\ln[/math] of both sides.

[math] y = \frac{1}{2}(ln(1+sinx))[/math]
[math]\frac{dy}{dx}= \frac{1}{2}cos(x)*\frac{1}{1+sinx}[/math]

>>8472655
I tried that, and then rearranged for y=ln(1+sinx)/2. Differentiating this to find the same answer as part 1nis where im struggling

That is just a joke version of this one. The books are good but many of them are graduate level.

And this.

>>8472605
yes

rupert and hyde

If I close my eyes the crane will act as a wave because it's not being observed, and will be propelled infinitely out of space and time.

-1/12

>>8472598
That expression is at a superposition. Please collapse the wavefunction by adding the missing parenthesis in either place.

the conjecture is false.

multiply the top and bottom by sqrt(3)-1

kill the denominator by multiplying with 1 and remembering the binomial formula

>>8472506
[eqn]\frac{\sqrt{3} - 1}{\sqrt{3} + 1} = \frac{\sqrt{3} - 1}{\sqrt{3} + 1} \frac{\sqrt{3} - 1}{\sqrt{3} - 1} = \frac{(\sqrt{3} - 1)^2}{3 - 1} = \frac{3 + 1 - 2 \sqrt{3}}{2} = 2 - \sqrt{3}[/eqn]

>on a hypercube

How do you define a point being "on" a hypercube?

>>8472469
On the surface of it. Like if you unfold a 3d cube, you get this. What would you get with a hypercube if you unfold it into 2d, and is that even possible without losing any surfaces?

>>8472475
If you unfold a 3d cube, you get 2d cubes (squares). If you unfold a 4d cube, you get 3d cubes. So in this sense, it's impossible what you're asking for.

>>8472454
Not really. Brainletacademy will not teach you why addition is commutative or associative.

No one who does not study pure math even knows why it is that way. Everyone just memorizes it.

Engys and physicsfags here who talk about 'intuition' are talking out of their ass because they just memorized shit. Ask one of those faggots to prove commutativity of addition of constructive reals and they will give you a blank stare.

Don't swallow the intuition meme. No one knows the 'why' of even the most basic mathematics until they know set theory and formal logic.

>>8472454
You don't learn math by memorization. So, your biggest problem is that you're treating it like it's a history class.

Understand the intuition behind the concepts, and understand why problems are solved the way they are.

By memorizing only certain paths you can take to solve a problem, if the problem doesn't immediately make it clear that it can be solved by taking a similar path, you will struggle with solving it. You'd be doing yourself a favor by looking at problems more openly like "what is this question asking, what is the meaning of the solution, and how does that meaning follow from the question" rather than, "well what method that I've previously done can I apply here."

I didn't understand trig for shit until I understand how it relates to the circle, and now it comes second nature to me.

Book suggestions to understand why?

Men arent supposed to overdose on estrogen and estradiol. Any steroid is a bad steroid.

Don't worry Trump will fix this. By removing all the regulations on endocrine disrupting chemicals in plastics to give people jobs we will all become gay.

>>8472376
Just don't use plastics

Good thing i never got a flu shot.

No.

Why are Americans so afraid of needles in themselves when they do this to animals for food?

You stupid thats wrong

>>8472307
I know you are but what am i

You are rude

>>8472250
You could start by not posting pepe the fucking frog. If you don't have the ability to start a thread with a math/science related topic yourself you have no right to complain. I'm sick of sci too but at least I keep it to myself.

you don't PhD in ochem to do that

>>8472008
shhh, don't crush his little dreams, let this fucking hopeless moron have something to cling to

>>8472003
You can do that with a PhD in Gender and Fat studies.

bias studies are for lib-arts faggots who can't into real science so they default to 'muh statistics

>>8472020
Well memed anon.

>>8472028
Well yeah, that's what I'm coming to realize. But I guess I'm wondering if there are any further neuroscience studies, maybe even brain scans, anything more empirical than simply this test? Are there any better studies out there? Because this is what I see presented most often as evidence for implicit bias by a lot of "social science academics" these days.

I have just written a paper solving the Goldbach Conjecture and it's about to be peer-reviewed by some hypergenius mathematician. I might be about to get rich and famous.

>groundbreaking research?

lel, I'm just trying to put the pieces of my personal life together for long enough to finally graduate

I could be doing some really interesting research if I didn't have to work while studying or if I didn't have to hurry up because I lost 2 years of my life due to health issues.

>>8471941
I'm doing research on improving one of the most commonly used vaccines in the world.
