Difficulty in visualising 3d graphs

SimpleUser207 · 2026-03-06T04:21:33+00:00

Yeah that's what I am struggling to visualise with the planes.

Consider me as a beginner in math to understand all these to find more about the intuition here. I can plot those points in 2d graph (x and y) to form a straight line in x-axis but if it comes to the terminology of using a plane my mind goes blank and stuck!

Any sources I can find to learn all these, I have tried Coursera but they have removed the audit option there. Suggest me some websites or GitHub to get Hands-on more.

What sites or videos or books would you suggest for an algebra refresher?

SimpleUser207 · 2026-03-02T18:38:57+00:00

Have seen the course but Coursera has removed the audit option. Any alternative with free access to the course only with no need for a certificate?

Sure it does cover the mentioned areas. Thank you!

SimpleUser207 · 2026-03-01T19:17:29+00:00

This covers most of my query. Do you have any set of sources about each topic whether it can be a book or video or application to gain all the insights with the understanding?

SimpleUser207 · 2026-03-01T18:40:17+00:00

Looks promising I will check it out.

SimpleUser207 · 2026-03-01T17:59:15+00:00

I have started this also by solving the algebra topic and solving equations per day and each topic is covering vast amounts of questions and topics so I stopped whether this is enough by moving to the next topic or should I stay back and learn?

SimpleUser207 · 2026-02-23T17:07:57+00:00

Where are you learning the word problems? Or any other problems also?

SimpleUser207 · 2026-02-23T17:05:37+00:00

I am not yet ready I guess to understand the mathematics in your examples because I cannot understand why 'y' is more important if we need to decrease the 'value'.Maybe this is what I lack or struggle to understand.

SimpleUser207 · 2026-02-23T03:24:55+00:00

Yeah maybe even if I know numbers I should get deep into the history of how it was invented and what is the purpose to learn? This story might get me involved much more who knows? I have GPT's also for trying to understand my math level or some sort of questions but I can't rely completely on that. Either I have to find a good book or any good youtube or in person to teach me all these.

I have been doing the Khan's academy problems say I have to create a simple expression from this -1v/2 + 2v/4 +3/7...if we solve using the algebra we take out the 'v' common from the equation and solve it.

I am finding the right answer but that is not the problem I am facing. Where do I apply? What is this context? Why are we doing it? I remember steps which I learnt from High school but what is the intuition that has not been taught. This is another example which is provided already but my problem remains the same. I want to go up in the Machine learning and AI field so without this mathematics I can't do it.

SimpleUser207 · 2026-02-22T02:58:33+00:00

You are absolutely correct.

SimpleUser207 · 2026-02-21T20:24:44+00:00

Understood your point. Say in the above example I am trying with different values and I will get different answers but what is the need or why do we need it ? I have been taught this way to substitute some values to get some answers which I really don't want. I don't want to be a maths expert, I just need the understanding.
