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: Solve dy/dx = 4x With y(0) = C, Then Evaluate y(x)
How the beat teaches it: The last lesson of Differential Equations: every slot solves the initial value problem dy/dx=4x, y(0)=C to get y=2x²+C, then evaluates it — separable equations, initial conditions, and integration, all in the final answer. Build that many notes anywhere in the kit.
This is lesson 24 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, “Finding an Equilibrium of dy/dt = y² - k,” covered solve y² - k = 0 for the Positive Equilibrium. It is the final lesson in this grade.
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.
