Differential Equations, Lesson 9: Using y(0) to Find A + B

Math skill: Find A + B From y(0) = Ae^(p·0) + Be^(q·0)

How the beat teaches it: Every slot gives a general solution y=Ae^(px)+Be^(qx) and the value y(0) — since e⁰=1 for any exponent, y(0) always equals A+B directly. Build that many notes anywhere in the kit.

This is lesson 9 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 Characteristic Equation,” covered find the Larger Root of a Characteristic Equation. Next is Lesson 10, Euler's Method — One Step.”

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.
