Triangle, three sides, angles sum to be 90°. Okay, makes sense, 30° per side. Got it.

Square, four sides. That means 120° 180°? 45° per side?

What the flying fuck?

What makes the sum of the internal angles change just because the number of sides change? Explain this bullshit to me please.

Might as well forsake everything but the positive integers, fagstorm.
If we can agree to keep fractions, this would be great. Negative numbers are useful as models, but they completely fall apart when applied to actual situations. Can you have -10 bottle caps? Can you have an a -5th element in an array (ignoring stupid shit that shitty languages sometimes do to make this work, like wrapping around)? No, you cannot. They are not real numbers at all, and are only esoteric academic products meant for ivory-tower kike paper-pushers without any experience in how numbers are actually used. Well, that or fucking kike bankers who keep pushing negative numbers at people and pushing them further and further into fucking debt.

There is no 0C, there is though 0°C, and once again, it isn't a pure scale. Perhaps you should be thinking of kelvin. There is no -1K. It is impossible to have less heat energy than that.

The natural universe has no need for negatives or infinity.

Signal and magnitude are different things, okay?
What you're saying totally ignores complex numbers and applications, including your so-valued computers.

No. Magnitude is an inseparable part of signal. Because if there are no magnitude, there is no signal.

Exactly! There is no negative/positive "infinity": Particle speed is limited by speed of light. And, AFAIK, physics is about to hit the bottom - i.e. the lower they get the more it shows that universe is discrete.

Can you have an a -5th element in an array?
Actually, you can define negative array indices, as indices from the end of array - i.e. modulo array length.

Magnitude is about size, scale, length, modulus and absolute value. That's not a signal. And then you take those roots, and analyze their signal, and they have meaning.

>>52
Distance between two objects can't be negative but it isn't limited to any size.
Observed time grew before, grows now and will grow while there is an observator.

The infinity isn't a real measurement, but it is some ``ABSTRACT BULLSHITHE'' that enables the study of how things behave as they evolve, grow, resonate, cycle, etc. It is possible to know limits for practical things like sum of GPs and the bounds of divide-and-conquer algorithms. Looking at the infinity you may not see how things end, but even so you'll be able to understand how fast things grow.

You don't seem to comprehend, but frankly, why do I care?

Hey goyim, why not reply the question?

You seem to be very mad about ``irrational crap''. Obviously, you can't have -4+5i apples, but you use that same concept to power your shitty 3D games. The fact that numbers don't have a tangible representation doesn't imply they're useless.

Now fuck off and go get fucked by a horny uncut ``priest''.

-4+5i is not even a fucking expressible with primitives. You're using a god damn vector and you fucking know it.

Performance comparisons with other rotation methods

This section discusses the performance implications of using quaternions versus other methods (axis/angle or rotation matrices) to perform rotations in 3D.

Results

Storage requirements
========================
Method              Storage
------------------------
Rotation matrix  9
Quaternion      4
Angle/axis      3*
========================

* Note: angle-axis can be stored as 3 elements by multiplying the unit rotation axis by the rotation angle, forming the logarithm of the quaternion, at the cost of additional calculations.

Rotation matrices have a problem of no longer representing rotations after repeating multiplications. The errors accumulate and soon they start to change the magnitudes of the vectors they rotate. With a quaternion, you can periodically normalize them so that they still represent rotations.

Read the rest of the article, they're good at vector rotating but worse than rotation matrices at rotation chaining.

Still, they're ``abstract bullshite'' that proves to be useful.

Enjoy your gimbal lock.

but..but...matrix multiplication of 4x4 matrices will cost you 4^3 multiplications, and 4^2 sums of 4 terms each, whereas quaternions require 4^2 multiplications and 4 sums of 4 terms each.

Exactly, and you'd use matrix multiplication, which is known to be one of the most trivial problems with efficient implementations in computer science.
