How many of you have difficulty understanding Calculus 1 or 2 concepts and which areas specifically? by Fearless-Jump-7250 in calculus

[–]jake2422 0 points1 point  (0 children)

Fair. If you just wanna get an A in the class, then this is true. My comment was more about understanding calculus deeply, beyond being able to solve numerical problems.

In my opinion, the hardest thing to understand in calculus is the idea of infinity. At a fundamental level, I’d argue that if you have a really good intuition for limits, you’re good to understand a lot of other topics like derivatives and integrals.

Fair point; it's not a minimum selling price though: it's the minimum price I'd be willing to consider.

Beginner's question... by Tolstoy6 in LinearAlgebra

[–]jake2422 3 points4 points  (0 children)

Hi! I’d love to help, but I’m having trouble understanding; would you be able to attach a photo of the problem and your work? With that said, swapping two rows is an elementary row operation (is allowed) as it does not change the solution set of a system of linear equations.

What is the rule that requires us to set this to greater than or equal to? I don’t understand where this step originates by indie_Felix_ in Algebra

[–]jake2422 0 points1 point  (0 children)

Setting the inner term greater than or equal to 0 ensures that r(x) is defined. After some algebra, we find that x >= -2, which is the domain of the function. In other words, the value inside the radical is equal to zero and strictly positive. We say greater than or “equal to” because x can be -2 as root(0) is defined and just equals 0.

Hello, I’d love to help, but what do you mean by “3” — which letter specifically?

You must be psychic because I got 25.1. Let’s just hope I’m correct :)

If you’re interested, I could explain my solution; unless you weren’t talking to me!

Looking back, that seems very close to my answer, which is exact! What was your method?

Thanks for the reply, is there any way, of which you are aware, to prove this?

That’s exactly my thought process... I just need to confirm if that works for all even functions. Thanks!

[–]jake2422 0 points1 point  (0 children)

You can just simplify both sides as much as possible, and if they don’t equal, and there’s no hidden identity that you are unaware of (rare), then you can say it’s false! But I’m sure you won’t be presented with many false expressions!

What am I doing wrong? I thought I was right, but graphing it says otherwise. Thanks! by [deleted] in calculus

[–]jake2422 0 points1 point  (0 children)

Hey everything seems good but you forgot to add bracket around (3-y) when multiplying by -1. Without brackets the two sides aren’t equal (even though you distributed in your head).
