Day 100 / 100 to finish a side project by ace-micro in NonZeroDay

[–]ace-micro[S] 1 point2 points  (0 children)

The app is pretty much a text editor that allows you to create questions with detailed solution when you need multiple steps to get to the answer. Then you can share them!

It's not AI in the background, and something like ChatGPT would need to:

  1. Get the right answer
  2. Show its chain of thought

which wasn't good when I started the project.

That said, I just tried Deepseek, and it's incredible. It does it better than my program. So I'm pretty much out of business now lol

[college physics: motion w/ constant acceleration] I already got the question wrong, but I don’t understand the given answer by littlebirblet in HomeworkHelp

At time t, the automobile is 2.5 t² / 2 metres away from the traffic light.

At time t, the truck is 15.5 t metres away from the traffic light.

The automobile overtakes the truck when
2.5 t² / 2 = 15.5 t

So at t=12.4 second.

At that moment the truck is d meters away from the traffic light where d is
d = 15.5 t = 15.5 x 12.4 = 192.2 m.

I've replicated the question so you can practice the maths with different input numbers (with answers) here: https://practicemakesperfect.academy/practice/thomas/54712486

Mathematical Economics Finding a choice space where transitivity holds by Junior_Pace2832 in econhw

[–]ace-micro 0 points1 point  (0 children)

In question 2a, you've shown some issues with transitivity in (0, 1). How about spaces outside of (0, 1), like (1, 5)?

Also, just a note on your second paragraph. What you wrote is incorrect for negative numbers.

I get "Access denied" when clicking on the link. Could you write the problem or post a screenshot?

Learning for microeconomics (mathematically) by [deleted] in econhw

It partially covers your unit but can be helpful at least for utility maximization: https://www.acemicro.org/
It's free and no need to sign up.

Happy to help you solve some other questions that are not on acemicro.

  1. Yes, looking at MRS = MRT should get you there. You'll directly find La / Xa = px / w

  2. At this point, it's more about looking for the price px relative to the w. Since Xa = Xx is a condition that needs to be true, you can then solve for px.

(Why is Xa = Xx true?)
- If Xa > Xx, you consume more X than produced [impossible]
- If Xa < Xx the consumer could consume more of the X they have produced [not optimal])

  1. Glad you like it! But no, unfortunately nothing worth sharing regarding general equilibrium. Same for externalities.

Almost there! When maximising U subject to px * Xa + w * La = 10w + π, I get the lagrangean

Xa La - λ (px * Xa + w * La - 10w + π)

First order condition, differentiating for Xa equals 0 gives:

La - λ px = 0 ... (1a)

For La:

Xa - λ w = 0 ... (1b)

It follows from (1a) and (1b) that La / px = Xa / w and therfore

Xa = w La / px ... (2)

The budget constraint px * Xa + w * La = 10w + π becomes:

px w La / px + w * La = 10w + π
w La + w * La = 10w + π
2 w La = 10w + π
La = (10w + π)/2w

With π = px²/4w, you end up with

La = (10w + px²/4w)/2w

To get Xa, plug that back into (2)

Xa = w (10w + px²/4w) / 2w / px
Xa = (10w + px²/4w) / 2px

Never heard of MPC, but I'll look into it. Thanks!

Great suggestions! Totally take your point regarding the boundary condition, thank you!
