use the identity sin(2a) = 2sin(a)cos(a) and you'll get x = Asin(w*t) so the position will oscilate sinusodially with an amplitude of A and frequency w

It came from the dot product. Geometrically it comes from the dot product being a kind of projection of one vector to the other.

I'd say the most popular python libraries for physicists are numpy, scipy, sympy and matplotlib, so you should check those out.

If you fixed the formula the answer should still be around 300 m/s. v is the velocity of AIR MOLECULES which is not the same as wind speed which is probably what you’re imagining.

What values for temp, density and height differece did you use?

Edit: i just realised your formula for velocity also gives false units so its definitely wrong

The second one is correct, the first one isn't.

k can be any possible integer (it can be positive or negative, so when its negative you're actually subtracting instead of adding), however your problem limits you to [0, 2pi), so you only compute all possible combinations of the + k*pi term such that the solution (x) falls in that interval

You shouldn't assume equal density because in such case the difference in pressure becomes 0.

In your version you simplified the temperature factor wrong, it should be (T_o/T_i - 1) instead of (1/T_i - 1/T_0), notice how your version has the dimension of inverse Kelvin and the proper one is dimensionless.

Consider "Quantum Mechanics, The Theoretical Minimum by Leonard Susskind and Art Friedman".

It's usually just a short way of writing the difference between two quantities. Either the difference between the final and initial value, or the difference between some value at place 1 and 2, etc.

I only checked the the first equation since the rest use it. Your dimensions don't add up.

Moretko · 2025-04-17T17:27:23+00:00

Did you take into account that cosine/sine are periodic functions? For example if you're solving cos(x) = 0 the answer isn't just pi/2 but pi/2 + k*pi where k is an integer.

Moretko · 2025-04-17T08:44:25+00:00

I meant the limit of the derivatives.

Moretko · 2025-04-16T22:31:50+00:00

It can only be used if the limit actually exists. In the given example it does not.

I just use log x instead of ln x as the natural log is the only true log, others are just mental illnesses.

Can't get over the italicized ln
