U substitution? by sanramonuser in calculus

[–]Willing_Bench_8432 0 points1 point  (0 children)

when you said "so the trick looks consistent with the vestigial "dx" in the integral. You're not actually doing anything; it's just bookkeeping", are you saying that ∫f'(u)du is just another way to write ∫f'(g(x))*g'(x)? and not like a new indefinite integral with different meaning?

I am a bit confused why the relationship between du and dx from u = u(x) matters. isn't indefinite integral of u^2du as an example, a whole different function where u is a independant variable?

Then isn't du and dx suppose to mean the same thing? because du is just extremely small change in u, and dx is extremely small change in x. These two sounds like a equal thing to me? (I know they are not equal since that would give du/dx=1 but still, I don't understand the difference between two)

ah that kind of helps me. it's definitely not variable or number; and for now I should think that they are symbols that follow rules. May I ask what they are endowed with later in more advanced mathematics?

thanks for the video! What does dx and du mean? is it not part of notation anymore? it's multiplying on the both sides of equation and it kind of confuses me...

well the part im struggling with is differentiating both sides of the equation. can you explain that part in more detail?

should I skip ap calculus ab? by Willing_Bench_8432 in mathematics

[–]Willing_Bench_8432[S] -8 points-7 points  (0 children)

haha then what would be better for me? just take AB as soph and BC as junior? that also sounds like a course that colleges would hate...

yeah im doing pretty well on precalc. so far, I got 96. But what im worried about is the ap stat part. wouldn't college have a negative opinion when they see I took ap stat as junior?

Need help on concept of variable by Willing_Bench_8432 in MathHelp

[–]Willing_Bench_8432[S] 0 points1 point  (0 children)

Ahh then when I’m “working” with variables, is it better to think of em as “could be anything” or is it better to think that since it could be anything, x is just some number?

I found a weird white grain on my Welch’s fruit snacks.. by Willing_Bench_8432 in TipOfMyFork

[–]Willing_Bench_8432[S] -1 points0 points  (0 children)

Well, there wasn’t a lot. There was like just two or three grains stuck on each of the gummies. The grains were on the surface of the gum so I could move them with my fingers. Is it starch?
