Geometry is a branch of mathematics that explores the properties, relationships, and measurements of shapes, space, and spatial relationships. It deals with points, lines, angles, surfaces, and solids, as well as their interconnections. Originally focused on practical applications like surveying and construction, geometry has expanded to encompass abstract concepts and plays a crucial role in various fields like science, art, and architecture.  

OnRamps PreCalculus: Using a creative and connected approach, you will deepen and extend your knowledge of functions, graphs, and equations from your high school algebra and geometry courses so you can successfully work with the concepts in a rigorous university-level calculus course. This course is designed to emphasize conceptual understanding of mathematical definitions and develop logical arguments with your peers. 

Calculus is a branch of mathematics focused on continuous change and the study of derivatives (rates of change) and integrals (accumulation of quantities). It provides tools to model and analyze systems where variables change, making it fundamental in various fields like physics, engineering, and economics.
