4/4 ×2
Drag rhythmic values into up to 8 beat blocks per line to build a drum groove, or click a tile then click a block to place it — handy on a trackpad.
Math skill: Compute W = y₁y₂' - y₂y₁'
How the beat teaches it: Every slot gives two functions y₁, y₂ — the Wronskian tests whether they're linearly independent solutions. Compute it, then evaluate at the given x. Build that many notes anywhere in the kit.
This is lesson 17 of 24 in RockBlocks Math, Differential Equations, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “The Order of a Differential Equation,” covered find the Highest Derivative's Order. Next is Lesson 18, “Laplace Transform of tⁿ.”
Every slot above (A, B, C, D) is its own question, and it’s a real, blank RockBlocks beat the whole time — the same drag-and-drop tiles, kit, tempo, sheet music, and drummer view as anywhere else on the site. Tap ❓ Questionin the corner to read the current slot’s problem, build your answer right in the grid, then tap ✓ Check Answerto grade it. Once you’re done, keep going: expand the beat, drop it into a Stack, or save a copy to your own page — nothing here overwrites the lesson itself, so every visitor still starts from the same blank slots.
