f=6x-2 is just one example. You would need to show that no other f exists.

It seems we have different interpretations of what ∫f²dx ≥ 4 means. I read it as: no f exists for which ∫f²dx is less than 4.

What is the proven in the article is that the minimum of the LHS is at most 4 and at least 0.

by yobbo 4y ago
Yes. The maximum of the RHS is not the minimum of the LHS.

> The longest inequality on that page is true for all a, b If you agree with this, then you why do also believe some particular a,b proves that ∫f²dx ≥ 4?

The article claims the RHS maximum is the minimum for the LHS. > ... you show that the integral (the LHS) is greater than our equal to zero. The article adds a function g, and uses (f+g)²≥0. It then picks a random g (g=ax+b), such that i

It's not true if we pick a=0 and b=0?

Audiophiles sometimes claim they can hear artefacts of the "low" sample rate 44.1 kHz, and only 16 bit samples. Nowadays there exists audio files recorded in up to 96 kHz with 24 bit samples.

With A/B tests, the only decisions you can make are among alternatives that are very close to the base alternative. Generally, you can only generate data and do experiments based on your present state.

In some degradation curves for lithium batteries, it looks like degradation is linear down to 80% over around 150 cycles. From then it degrades to 0% over another 100 cycles. From the curves in your link, it seems EVs have fewer cycles per

A single home with all of its roof covered in solar panels is barely self-sufficient, even during the summer half-year. It can be, but it depends on usage.

That doesn't answer the question. Why not move all of it out?

Yep. As long as interest rates are held below the inflation rate, this outcome is inevitable.

When there is deficit of supply, prices stabilize at the margin where increasing price also decreases the quantity sold. Monopoly prices = increasing prices reduces revenue. Also look up "rent seeking".

A locked-in user has a long (or very long) economic lifecycle, whereas a widget has a short lifecycle. "Software engineering" is probably subsidized by borrowed money aimed at growing locked-in userbases and therefore valuations.

If there was lack of supply and excess demand, it would show in higher pay.

It's the price of milk, bread, and meat that is causing CPI to rise. Not PS5s.

> It's not new demand - it's less supply. Iirc, it is true that fossil fuel production peaked in 2019. However, it is still very close to 2018 levels. Demand, measured in currency units, has increased by a lot since then.
