Calculus II, Lesson 1: U-Substitution

Math skill: Evaluate ∫2x(x² + c) dx Over [0, 2] Using u = x² + c

How the beat teaches it: Every slot gives ∫[0,2] 2x(x²+c) dx — let u = x²+c, so du = 2x dx, turning the integral into ∫u du between the two u-bounds. Build that many notes anywhere in the kit.

This is lesson 1 of 24 in RockBlocks Math, Calculus II, a free course where every lesson turns a math idea into something you can count, hear, and play. It is the first lesson in Calculus II, so it assumes no prior math or drumming. Next is Lesson 2, U-Substitution With a Cubed Inner Function.”

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.
