Curioso: Si asumimos el diámetro de la tierra = 1 unidad y como el diámetro de la luna es 27,3% el de la tierra , entonces (ver la figura) si colocamos la luna encima de la tierra y la tierra en los catetos la hipotenusa es el número «phi» la "proporción áurea"

Accomplish beginning calculus. Have more understanding of the subject and its applications in other fields.

@BilselY Good work!✅✅

#math problem 13-05-2026 Calculus: Recursive equations with nested radicals. Find x(n) ( "x" as a function of "n")

@m_j_wiener That's it. Correct.

@MathMath901 I like how it simplifies as you repeatedly square both sides. You get 1+2*(2^n)*sqrt(x)=3, or x = 4^(-n).

@nntaleb ✅✅

@MathMath901 x(n)=1/4^n

@MatthewAlbano8 ✅✅

@MathMath901 I have not proven it, but by the basic problem solving strategy of computing a few specific examples to observe a pattern we have x_n = 1/4^n, for all n = 0, 1 , 2, ...

@cesscabral ✅✅

@MathMath901 Step 4): if x>3 then (3-x) is negative => you must change > to <

Vix.cpp is getting closer to the kind of developer experience I always wanted for building native applications. Create the project, build it, run it, and focus on the product instead of fighting the setup. Docs: docs.vixcpp.com

@stairw2hven @MicKowal @geogebra well, thanks for the info.

@MathMath901 @MicKowal @geogebra Before they were bought they sometimes commented some post or liked it, but now neither.

@kubantemriuk Good!

@MathMath901 As 5<k<6, k = 5 + (45 - α/3°)/60 = 5+3/4-α/180° = 6-α/30° 1/4 =(6-1)*α/180° = 5α/180° = α/36° α = 9°, t = 45-α/3° = 45-9/3 = 45-3 = 42 It is 5:42 or 17:42 (b/c the clock is based on the 12-hour system)

#math problem 10-05-2026 Time is the same in a relative way,but you're older.

@MathMath901 Define the rectangle as the function f and the circle as the function g. f(x-1)=x-5, g(f(f(x+5)))=x-2 f(x-1)=x-5=(x-1)-4, so f(x)=x-4 f(f(x+5)) = f(x+1) = x-3 g(x-3) = x-2 = x-3 +1 g(x) = x +1 g(2002) = 2003

@stairw2hven @MicKowal @geogebra don’t appreciate?? That's odd.

@MathMath901 @MicKowal Yes, @geogebra , but I tagged them only sometimes because they don’t appreciate to be mentioned since they were bought.

@DeAtxa correct.

@MathMath901 6pi/(3+2sqrt(2))

@MicKowal @stairw2hven i guess, geogebra.org

@stairw2hven @MathMath901 What is an application?
