Best ResponseYou've already chosen the best response.5yes, for example multiplying all the coordinates by "2", blows up the shape by a factor of 2

Best ResponseYou've already chosen the best response.1Yes, I remember reading about something similar, we just use left instead of right, down instead of up, etc for transformations at least.

Best ResponseYou've already chosen the best response.1It seems like it could be interpreted as a reflection, but this is a good question I've thought about this sort of thing a lot.

Best ResponseYou've already chosen the best response.5yeah multiplying x coordinates by 1 is indeed a reflection about y axis

Best ResponseYou've already chosen the best response.1I think in some sense, negative numbers are sorta just a special case of complex numbers. If we look at subtraction in a literal sense, we can never take anything away from nothing, so 0x=0 could be defined in this way, or simply be undefined since it's nonsense. But yeah, I guess when I think of reflection if we think of smoothly transitioning the scale factor from 2 to 1 to 1/2 to 0 to 1/2 to 1... we can sort of imagine a scale turning an object inside out through itself. So it depends on if you want to allow this sorta thing or not haha.

Best ResponseYou've already chosen the best response.0Multiplying both by 1 should flip them across both x and y axis.

Best ResponseYou've already chosen the best response.5wow! yeah it is useful to allow as we can use the same formula of scaling for reflection also... wonder if it can be extended for any arbitrary line ?

Best ResponseYou've already chosen the best response.5reflection over y axis : scale by (1, 1) reflection over x axis : scale by (1, 1) reflection over y=x : scale by (1, 1)

Best ResponseYou've already chosen the best response.5reflection over y=mx may involve complicated expressions for scale factors i see

Best ResponseYou've already chosen the best response.5Looks below sequence of transformations work for reflection over any vertical line \(x=k\) ``` translate(xk, 0) scale(1, 1) translate(k, 0) ```

Best ResponseYou've already chosen the best response.1well, scale factors are SCALE means take   for it , other wise negative is a reflection so if you wanna scale by ( negative something, negative something) the negative is a direction which might do (translate, reflection,rotate) and the something as scalar itself do the scale hmmm even though i cant see any harm in doing it why cant scale be both scalar and a movement ? (translate, reflection,rotate) this is should be good in maps encryption. do you have a special case or something ?

Best ResponseYou've already chosen the best response.5basically the tool im using has no reflection feature. so im thinking of achieving it using below transformations 1) translation 2) scaling 3) rotation

Best ResponseYou've already chosen the best response.1oh you wanna reflection like symmetry or what ? could you give an example ?
