Yes, I know that on the last page I found the answers. Describe how you solved it. The "scientific method"?
Of course not.
x is the number of students.
x=x/2+x/4+x/7+3

that's a different conversation.
ZS: there were no mega-brains back then
Natural is the way we were taught in Russia, i.e. whole and greater than zero.
Careful with definitions, you may offend people's feelings on some social or religious grounds.

Yep.
Since real life does persistently seep into this spherical-vacuum branch, I venture to throw in some "mind-blasting explosives".
Why here? The answer is simple: all the local intellectual mafia elite come here.
// Well, I'd like to raise the intellectual level of the community...
// And so I try to regularly introduce the sensible, the good and the eternal into the ranks of those present. And also the crazy, the unhinged, and the zen-in-the-moment.
Therefore. Before you scold me, ban me for being off-topic and delete me "off-topic", I beg you to download and read 20 pages. Specifically from 25 to 45.
If you do not like it or find it harmful - you can stonewall delete the post and put in a cycle with nails. (; But dare not before. ;)
// The text of the practical exercises must also be read. Perform on first reading is not necessary... :-)
So, I bring to the attention of regulars (and not only) a seminal book on Leary's outlines.
Robert Anton Wilson. The Psychology of Evolution.
It's a real kick-ass book. Hold on tight...
;)

There is also a torrent (I put in the trailer). Format: DjVu, PDF, DOC.
Therefore. Before scolding, banning for offtop and deleting "due to irrelevance", a small request: download and read 20 pages. Specifically from 25 to 45.
x'=x*cos(f)-y*sin(f);
y'=x*sin(f)+y*cos(f);
y=k*sqrt(r^2-x^2);
Express y' over x', i.e. get the function y'=F(x') so that the function has no x and y and determine the limits of x' at which y' exists.
This is a function of a rotated ellipse.
If anyone is not lazy...
It won't work. The general form of the equation is:
a1*x'^2 + a2*y'^2 + a3*x' + a4*y' + a5*x'*y' + a6 = 0;
Ideally, all the coefficients can be expressed analytically, but you can't get to the form y'=F(x').
In order to estimate the range of values, we can take the derivative at the known coefficients.
It won't work...
It has to be, you have to believe:) Maybe not through deductions, maybe it will come to pass.
