# MathBode-ExponentialInterest: Exponential Functions Domain

Compound interest and exponential growth problems from the MathBode benchmark.

This dataset is part of the **MathBode** benchmark, which evaluates the dynamic reasoning capabilities of large language models (LLMs) by treating parametric math problems as dynamic systems. Instead of testing static accuracy on fixed problems, MathBode sinusoidally varies a parameter and measures the model's response in terms of **gain** (amplitude tracking) and **phase** (reasoning lag), analogous to a Bode plot in control theory.

## About This Domain

This dataset contains **Exponential Functions** problems specifically, with approximately 9,408 prompts covering:

- **3 question variants** with different constants
- **Sinusoidal parameter sweeps** at 5 frequencies (1, 2, 4, 8, 16 cycles)
- **3 phase offsets** (0°, 120°, 240°) for statistical robustness
- **3 amplitude scales** (0.5x, 1.0x, 2.5x) for non-linearity testing
- **Chirp signal validation** with continuous frequency sweeps
