Hey I'm getting out of the military soon and was wondering what would be a great way or method to study mathematics and science?

Do you guys any known effective methods that help you out and would like to share them?

I've heard of the Cornell method of note taking and the Pomodro technique anything else worth mentioning?
>>
>>7783935
Best advise I can give is to be curious, interested and not afraid to ask questions that might seem to have obvious answers.

If your IQ is less than two standard deviations above the mean, don't even think about it.

Pomodoro technique has worked great for me. I recommend it.

Great news today! NASA split the CRS-2 contract for ISS resupply three ways, between the existing SpaceX Dragon, Orbital Cygnus, and (finally!) new space plane Sierra Nevada Dream Chaser! A space plane will once again fly to orbit!
>>
>>7783911
Dream Chaser had originally lost the crew contract to SpaceX and Boeing CST-100 (now called SpaceLiner). Now it will be repurposed for cargo delivery and low-stress return, due to its high lift gliding return profile.

The Dream Chaser is the culmination of almost forty years of design and refinement, starting from the HL-20 lifting body design. It will be great to see it get off the drawing board!

It already had a successful glide test, with another coming up shortly. The first orbital test launch will be sometime in 2017-18, now that funding is coming in again.

Need some help with this. I know I can replace z4 with exp(4ix) which gives cos(4x)+isin(4x).

The most I am able to figure out is maybe replace z4 with the cos/sin, but how I don't know how to move on.

Many Thanks.
>>
Let z = a + i b

[eqn] \frac{1}{1 - (a + ib)^4} = \frac{1}{1 - (a + ib)^4} \frac{1 - (a - ib)^4}{1 - (a - ib)^4} = \ldots [/eqn]
You should be able to do the rest.
>>
[eqn] z^4 = e^{i4x} [/eqn]

[eqn] \frac{1}{1 - z^4} = \frac{1}{1 - e^{i4x}} \frac{1 - e^{-i4x}}{1 - e^{-i4x}} = \frac{1 - \cos(4x) + i \sin(4x)}{2 - 2 \cos(4x)} [/eqn]
[eqn] \Re \left( \frac{1}{1 - z^4} \right) = \frac{1}{2} [/eqn]
>>
>>7783887

Since $|z|=1, {\bar z}=1/z.$ Let $w=1/(1-z^4).$ Then $Re(w)=(w+{\bar w})/2=(1/(1-z^4)+1/(1-1/z^4))/2 = 1/2.$

Oh thank you I'm new to 4chan

I don't know how to feel about my maths teacher, /sci/. I feel like he's actually holding me back more than helping me. He's the 'funny guy' type teacher, and while he genuinely is funny, I think he isn't doing nearly enough work. I only have about six months to my exams, like.

He gets into slagging matches with students a lot, and he doesn't get enough maths done. My maths skills are poor enough as it is. When he's actually doing maths he's quite good at explaining it, but he laughs and jokes too much.

I don't...
>>
>>7783839

Why on earth do you need your maths teachers help? Just do everything yourself and use the internet. High school math isn't difficult.
>>
>>7783847
I still need his help for stuff, anon. Sometimes the book doesn't explain a concept well enough, or else I get stuck on a past exam paper question.

I'm getting really sick of the 'laugh joke' thing. I put on a front that I'm enjoying it (though I do genuinely laugh once in awhile), but I'm too nervous/scared to say anything.

I don't know what to do.

Still keeping it simple, square root function, more python jargon however.

Newtonian method if I'm not mistaken.

The conditional statements [if statements] are there just for error handling, and do not really play a part into the algorithm.

Why not make the pizza a different shape in the first place? Ovens are mostly square/rectangle anyway.

$\nabla \times \vec{B} = \mu_0 \epsilon_0 \frac{d\vec{E}}{dt}$ for source-free Maxwell, so yes.

>Microwaves?
Depends on the frequency of the discharge.
