| Topic | Chain Rule |
| Type | Find curve equation from derivative |
| Difficulty | Easy -1.3 This is a straightforward collection of basic calculus exercises testing standard techniques: chain rule, product rule, simple integration, and finding a particular solution. All parts are routine recall with minimal problem-solving, requiring only direct application of learned rules with no conceptual challenges or multi-step reasoning. |
