Z* is a bad notation for Z\{0}. Usually, the * means the set of invertible elements. In Q and R, all numbers except zero are, but in Z, only ±1 are invertible.

funny enough, if you are using the wheel of real fractions, 1/x actually *is* continuous at x=0, which is possible because this algebra satisfies -∞ = +∞.

Ecclesiastes 7:3 Sorrow is better than laughter; it may sadden your face, but it sharpens your understanding. Proverbs 14:13 Laughter might hide your sadness. But when the laughter is gone, the sadness remains. If you want to know the Truth follow Jesus.

Your a mathematician you shouldln't be involved in such problems or not most of the time at least focus about the main structure of math which is analysis and set theory and geometry best of luck those are to some extent are only mere puzzles.

The method I have always learned is convert the graph to vectors and apply a linear transformation, which basically does the same thing.

If you have leart rotate metrix, you can easily get the formula what video get. And you can let u= xcost-ysint v= xsint+ycost This is more readable.

You talk about parametric graphs, OK. But what about rotating a function for real, in the form y= f(x), since it ist definite?

@akirakasinata-fk8qyАй бұрын
Well my graphics calculator certainly does Not let me put values of y on both sides of the function and then draw a graph; It's seams pretty set at Y=... As it's only form. So though the principle in this video seams interesting it's clear you have software which lets you do that, which the standard maths stuff doesn't. Both the software and calculator I have also specifically will not process multiple y values equalling a single x value. Hence the difference in plotting √X to X^2 ; √X should just be the 90° pivot of x^2, but it won't produce the two values of y no matter how I present it (i.e. X^0.5 Vs √X)

I found an easy way to put it into Desmos, have different equations: defining the original function before rotation (“f(x)=…”), defining a variable (“b=…”) and the function after rotation. And preferably, put it on “degree” mode. For the parabola at a 45º angle, it would be: f(x)=x^2 b=45 x*sin(b)+y*cos(b) = f(x*cos(b) - y*sin(b)) Change variable “b” to however many degrees rotated you want and change the “f(x)=…” equation to whatever you need to change it to and the rotated equation will update with it. Setting it up like this will also make it so u only have to update less things whenever you want to make a change

Sitting in my freshman math class, I came up with this projection concept but I had no idea this existed. My approach was evaluating how complex numbers would work with this creating a spherical or torrid geometry. The curvature would be flat because the number line extends to infinity. In other words, this concept as a "number line" would be the same for finite ranges.

This reminded me, that in computer graphics, coordinates are represented using matrices and you can compute rotations very easily. If rotation is in angles however, this method is required.

I wrote a complex number lib, and you can just multiply the function in parametric form by (cos θ, sin θ). Works like a charm.
