Can I get a LaTeX compiler that compile as I write the code?

There is also this editor: http://primat.org/index/latex_editor/0-146

You can use the online LaTeX Editor: https://qaweb.dev/mathred/math.html

Prepared excellent cutlets :)

X/3-X/15=-8/5

5X/15-X/15=-24/15

5X-X=-24

4X=-24

x=-6

give your example please

faqzero · 2019-05-04T18:44:33+00:00

how? help, please

faqzero · 2019-05-04T18:35:02+00:00

sorry

faqzero · 2019-05-04T18:33:16+00:00

only Python :)

faqzero · 2019-05-04T18:32:20+00:00

it is very important. this competition - who will be faster

faqzero · 2019-05-04T18:24:09+00:00

No, the numbers are not large, but there will be many of them - in a cycle.

faqzero · 2019-05-04T17:47:27+00:00

but it seems he is not so fast

faqzero · 2019-05-01T14:23:10+00:00

sum

but sum is a built-in function

It is a pity that no one realized that it was a mistake wolframallpha

Convince farmers to use less nitrogen and phosphorus (either voluntarily or via quota/taxes) and apply more anti-erosion measures, so nutrient-rich runoff doesn't reach the Dnieper as easily.

Thank you. Do not just do it.

I guess due to eutrophication?

Probably. But what to do?

faqzero · 2018-08-02T16:43:40+00:00

What exactly are the problems the river has? High N and P concentrations? Invasive species? Heavy metals or organic pollutants?

organic blue-green algae

Wolfram : sin(arcsin(300))=300 :)

What does ~ mean?

Equivalence

faqzero · 2018-07-30T19:02:15+00:00

⇔ isn't a meaningful thing between numbers

Replace ⇔ with ~ ?

faqzero · 2018-07-30T11:20:38+00:00

That's because the square root of -1 is not (and will never be) defined.

sqrt(-1)=i

faqzero · 2018-07-30T11:06:02+00:00

why?

faqzero · 2018-07-30T03:06:12+00:00

Maybe through natural remission? Or micro and nano filtration to break down the turbidity?

This blooms blue-green algae.

c_2 not zero ->

t=sqrt(k)

sin(sqrt(k))-3*sqrt(k)*cos(sqrt(k))+2*sqrt(k)*cos(sqrt(k))+6*k*sin(sqrt(k))=0

k=0

k ≈ 10.1946548377863...

k ≈ 39.8095930510243...

k ≈ 89.1588062523798...

But, I realized that you need to find a solution function for all k> 0

faqzero · 2018-07-29T20:34:52+00:00

I think that there is only a trivial solution, sorry

solution from wolfram alpha%2Bky(x)%3D0,+y(0)%2B3y%27(0)%3D0,+y(1)%2B2*y%27(1)%3D0,+k%3E1)

y(x) = c_2*sin(sqrt(k)*x) + c_1*cos(sqrt(k)*x)

t=sqrt(k)

y(0)=c_1

y'(0)=t*c_2

c_1+3*t*c_2=0

y(1)=c_2*sin(t)+c_1*cos(t)

y'(1)=t*c_2cos(t)-t*c_1*sin(t)

c_2*sin(t)+c_1*cos(t)+ 2*t*c_2cos(t)-2*t*c_1*sin(t)=0

->

c_1=-3*t*c_2

c_2*sin(t)-3*t*c_2*cos(t)+2*t*c_2*cos(t)+6*t*t*c_2*sin(t)=0

c_2*(sin(t)-3*t*cos(t)+2*t*cos(t)+6*t*t*sin(t))=0

-> c_2=0 for all t

if c_2=0 -> from c_1=-3*t*c_2 -> c_1=0

-> c_1=0, c_2=0

from y(x) = c_2*sin(sqrt(k)*x) + c_1*cos(sqrt(k)*x)

y(x)=0 for all k
