What is "abscissa" and "ordinate"?

Is “abscissa” the same as “x-coordinate”? Is “ordinate” the same as " y-coordinate"?
“Abscissa” and “ordinate” appear in the articles such as scale(). They looks like something I should understand before reading the articles, but I don’t seem to have suitable knowledge. I’ve read various explanations about these words, but I’m still not sure whether each word corresponds to each word or not.

I’m trying to understandtransform because of an instruction in “CSS first steps”, which requests trying this property.

Hello @user-p

yes you are right

scale used to resize the element so to enlarge it or shrink it and it could enlarge it horizontally and shrink it vertically and visa versa

if you need to learn more about it then you would learn about vector and matrix in math

hope that help and have a nice day :slight_smile:

Hi @justsomeone, I appreciate your reply.
If you don’t mind, I’d appreciate if you could tell me the following:

  • Why did you think that each word corresponds to each word?
  • Do you think they are exactly the same( and if possible, why)?

Don’t worry about this question any more, if you have some reason in your mind. Just in case, don’t worry about the possibility that I believe something only by your reply.

I don’t know how to say this but, what you gave has doesn’t work for me without such thing. This time I aim to solve this question for a bigger question, so I try to understand stricter about it. Before getting your reply, I already found words like what you gave me and I explored there to some extent. In such a situation, I’ve been keeping research. In other words, I’m not just keeping waiting for an answer, so I think giving me time is one of your options, even if you try to help me.

I’m sorry if I’m saying too directly or impolitely.

Hello @user-p

first never be sorry for any question you ask i am glad to help as much as i could

from the scale link you mentioned this one https://developer.mozilla.org/en-US/docs/Web/CSS/transform-function/scale

The scale() CSS function defines a transformation that resizes an element on the 2D plane.

2D is short for 2 dimension

also it said Because the amount of scaling is defined by a vector, it can resize the horizontal and vertical dimensions at different scales

This scaling transformation is characterized by a two-dimensional vector. Its coordinates define how much scaling is done in each direction.

so the amount you provide determine the scaling for each coordinate

if you notice the first image show you how the small rectangle scaled to be the bigger rectangle

also notice there another version of scale scale3d()

in light way explanation of how scale work
let us assume we use scale(2,0.5) that mean it will double it size horizontally and shrink it to half vertically

so if an element has size 10 pixel x 10 pixel the result would be 20 pixel x 5 pixel
so imagine it as you double each pixel in x-axis and divide each pixel by half in the y-axis

check this link from the w3c website the guys who make the web standard
https://www.w3.org/wiki/CSS3_2D_Transforms#Scale

why i said you need to learn vector and matrix from math cause that how things work in the backend

and i do not mind to be corrected if i am wrong about anything as that how i learn

and by the way i am just learner same as you and even if i become one of those expert i would not mind to learn anything from anyone and i did not get offended if you told me that i am wrong about something

so feel free to hit me with any question anytime and the delay of replay cause i am a learner so i am volunteer same as others so sometime i am busy sometime i look for answer sometime lazy :wink:

by the way it better to click the replay to the person comment so he/she get notified by email when you replied

let me know if you have any question and will be happy to help with it and have a nice day :slight_smile:

Hi @justsomeone, I appreciate your kindness. Please forgive me about having confused you and planning to stop this topic without some appropriate explanation. I’ll read your messages again slowly and carefully, but it is unlikely that I reply something about them anymore.

My tentative conclusion

Probably they are not the same thing and the words which is used in different places. However, probably it is possible to express something similar or the same thing by them. I’ve already thought about the possibility your agreement meant something like this. I’ve also thought about the possibility they are in the field of geometry. However, at least now, it is rather better for me to avoid looking over the field for researching their difference(that’s almost impossible in the first place). After the reserch, I came such conclusion.

I also appreciate letting me know the state.

you very welcome and everything in computer science is math
and in my humble opinion it would be better say what inside your brain and what you thinking of better than i guess

and since you asked about how scale work i told you how things go in the backend even you do not need to do it to be able to use it but of course knowing it would make you use it in better way

and please be direct in your question and i am glad to offer any help as much as i know and have a nice day :slight_smile:

Hi @justsomeone, I appreciate your kindness. Don’t worry about this question any more.
I got enough hypothesis for my present self after my last post. I planned to report about it. However, … I decided not to create such a reply at least. I may add a post on this topic, but unless I reply you directly(Maybe could I do that by this post?), that doesn’t mean a reply to you, and it is very unlikely that I will reply to you again.

Probably I couldn’t do that. When I reply to you, I will include @justsomeone clearly. Don’t worry about this problem for now, too.

if i understand you then i will not reply till you mention me by my name as @justsomeone

and happy coding :slight_smile:

Thank you for the link. That worked for me!

you very welcome @marckleser81 and have fun coding :slight_smile:

@marckleser81
That’s nice and I celebrate your first post.
@justsomeone
Probably yes, I always talk to you with the mention on this topic? I really pray you didn’t misunderstand something.

@user-p

not sure what you saying here but i am not sad or angry or offended or anything bad by any thing you said

all i ask that you go directly to the question as english is not my first language same as others in this community so direct question in simple english make things better for everyone

and have a nice day and happy coding :slight_smile:
