AP PRECALCULUS
Exponential Growth vs Decay Comparison
Compare exponential growth and decay side by side. Adjust the initial value and base to see how doubling time, half-life, and growth rate change. Includes real-world presets like compound interest and radioactive decay.

Logarithmic Scale Visualizer
Explore how logarithmic scales compress vast data ranges. Switch between Richter earthquake magnitude, decibel sound levels, and pH acidity scales to see real-world log₁₀ applications.
AP PRECALCULUS
Compound Interest & Continuous Growth
Compare discrete and continuous compound interest. Adjust principal, rate, time, and compounding frequency to see how A = P(1+r/n)^(nt) approaches A = Pe^(rt). Includes the Rule of 72.
