#math problem 23-07-2026 🖥️ The Exit Algorithm: Given the INPUT (the board) and the RULES, determine whether you: • Can reach the EXIT. • Conclude that no valid path to the EXIT exists. Don't assume the correct path is the obvious one. You may find a solution that seems counterintuitive, as long as it never violates the RULES.

To correct. Using triangle inequality. √17 + √10 > √53

Let vectors x=i+3j, y=i+4j, z=x+y=2i+7j Notice that A = √(1²+3²) + √(1²+4²) = |x| + |y| B = √(2²+7²) = |z| = |x+y| By triangle inequality, A>B.

#math problem 09-11-2026 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐥 𝐂𝐚𝐥𝐜𝐮𝐥𝐮𝐬 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧: Suppose a lumberjack cuts a wedge-shaped piece (W in the image) from a cylindrical tree of radius "r" by making two saw cuts toward the center of the tree: one horizontal and the other at an angle θ. How could the volume of this wedge be calculated using a single integral?

Please tell me I'm not the only one who remembers that whole Orion 117 theory thing.

Maths teaches life too. Sometimes a problem looks terribly complicated, so we start searching everywhere for the solution. Then we realise the answer was hidden in the question itself. Life is often the same. We don't always need more answers. Sometimes we just need to understand the question better. And yes, in both maths and life, we usually realise this only after making things unnecessarily complicated.

For the folks who still learn math from textbooks, this is a pretty good one on complex variables. I’ve worked a few exercises (slightly modified) from chapter 4, which I may post in the coming days.
