Course description
Start building visual patterns and discover formulas that govern them. Use these visualizations to compare sequences that show different growth, from linear to quadratic, exponential, and beyond. Define patterns and sequences recursively, and explore the fascinating shapes that emerge from the simplest recursive processes. And most importantly, see algebra like you've never seen it before!
