Integral of x³
(Published on 14. October 2024, 21:43 by Evan)
I wanted to make something math themed, as I'm currently studying mathematics in university. So, I hope you enjoy this simple puzzle!
RULES:
Renban lines: Pink lines must contain a set of consecutive digits in any order, without repeats.
Region sum lines: Digits on a blue line have an equal sum N within each box it passes through.
German whisper lines: Two cells connected by a green line must have a difference of at least 5.
Killer cages: Digits in cages must sum to the number in the top-left corner and cannot repeat.
XV: Cells joined by an X or V must sum to 10 (X) or 5 (V).
For clarity: The whisper and renban x's are each technically two different lines of length two intersecting each other.
Solution code: Row 6

Here's my solve of your puzzle. Didn't realize that the sum under the curve adds up to the 156. Lovely setting with that knowledge!

Very nice, I'm gonna share it with my students who have a test about integrals next week:-) Loved it a lot!
Tiny point though: integral boundaries do not match the area. But I regard this as purely cosmetic here. The curve resembles x^3, which is great. Fantastic rendition of the subject, a work of art!

Yes the boundaries are wrong... unfortunately having both "positive" and "negative" area would not have worked :((, but I still wanted the region sum line to resemble x^3.
Regardless, I'm glad you enjoyed it!

only when i read the comments did i click that the integral was more than cosmetic. Much wow - thanks for a gorgeous puzzle.

Fantastic the equation does work out to be the area under the curve. Very nice setting.

I'm glad you found that detail haha! It's not geometrically accurate, but I wanted to add a little something. - Evan
