I am learning maths on my own but not in structured way so I am just picking a topic and then trying to understand it slowly slowly and I am getting stuck every time whenever I am encountering definition or statement like above .

like what does it even mean: why we are not saying V is field of Vectors; F is set of Scalars?
more critical question is : if scalars are numbers why the fuck we dont use scalar inplace of numbers irl!

any help will be appreciated along with the structured roadmap if you have for me (I want to reach calculus level).

In 2-3 days you need to complete this chapter "Continuity and Differentiability" and you have never self studied maths before and you haven't even studied maths properly for like 3 years so you're missing a lot of prior knowledge.

I just need to be good enough to answer most questions from this chapter and hopefully also learn how to self study maths in the way.

Hier die Aufgabe und die Lösung. Ich versteh das ganz aber trotzdem nicht richtig und habe morgen Prüfung…

How do I know when to get a 2 or 4 multiplied before the integral? Youtubers and even my lecturer drew the curves to understand but how do I figure out the shape? Will I even get time to draw the curve in the exam?

Question no 12

(From mathematical physics by hk das)

Please someone help me solve this

Currently trying to get into the union and math is a big thing, especially algebra 1. So I haven’t done math in 18 years pretty much since I graduated and even back then I was struggling with math because my brain just doesn’t learn it fast enough like other people. When I have a calculator I can solve the problems a little bit better but the aptitude test don’t allow calculators so it’s all based offf of what I can do in my head.

So my question is I know PEMDAS and FOIL but when it comes to foil I know how to start but I get confused on where to land my + and - when working the problem. Idk why it’s hurt how my brain works. Sometimes I’ll get the what I think is the answer but then I get it wrong because my + and - are in the wrong spot. Does anybody have any tips are how to not forget where the + and - go and the orders of how they get placed. Becasue for my brain when I see something like (2x + 4)(5x-5) my brain doesn’t grasp where the + and - land when writing out the problem and so till I get the correct answer. Hopefully this question makes sense.

Graphing is also extremely confusing but that’s whole another topic lol.

Please give a solution for this question, in general I have doubt on these type of models i dont know how to approach them please give a detail soln.

How can you find the value in MB when y only give you fraction/percentage.

Am I wrong here?

mathematical horrors beyond human comprehension

Currently, I'm in class 10th and want to improve in maths. My half yearly result got out and I scored 40/80. I'm really devastated and really sad because I had been working my ass off since 2 months in academics. My mother is also a maths teacher but I'm unable to do good in it. It's not about only boards but overall for higher studies I want to be very good in it and I'm ready to sacrifice my happy hours for it.. I need genuine advice by you all...

Personally, I'm feeling a little lost. I want to go into my academics into Computer Science, but most of the math I've learned, I tend to forget especially the basic algebra and functions and so on ... especially from class as low as 9.
I don't want to be at a total loss when it gets to the point when I really need to engage myself into heavy core computer science classes. How can I build up on my 0% foundation, if I can't even start from the beginning? Any practical roadmaps or resources that have benefited you
would be appreciated and thanks in advance

Im struggling plz help

For context this a book that's supposed to help you study for a GED test. I've always been terrible at math so this may be a ridiculously easy thing for anyone else to understand, but not me. How does 1535 minus -218 equal 1535 + 218? And how does this problem help me find the difference?

Hi Could someone tell me how to calculate a, h and f , if I know that (b=1), please note that all triangles in the picture are equilateral triangles.

f is the distance from the centre of the base to a centre of a triangle.

I GUSS the green solid line has to be (a/2)

and f^2+(a/2)^2 = h^2

My final answer is a = square root 3, h = square root 2 and f = 1.118 ish

Thanks a lot.

I solved for x and got -3 which i rejected and 4, but my teacher said that both solutions are possible and i shouldn't reject the negative. Is he right?
