Calculus

Explore the fundamental concepts of calculus through interactive visualizations

Why Calculus Matters

Calculus enables you to model and analyze how things change, laying the groundwork for advances in physics, engineering, economics, and data science.

  • Analyze motion and forces in physics
  • Optimize functions in engineering and economics
  • Model growth and change in data science

Introduction to 3D Functions

A function of two variables, f(x,y), can be visualized as a surface in three-dimensional space. For each point (x,y) in the domain, the function outputs a value z = f(x,y), creating a point (x,y,z) on the surface.

These surfaces help us understand concepts such as:

  • Partial derivatives and the gradient vector
  • Local extrema and saddle points
  • Double integrals and volume calculations

The interactive visualizer allows you to explore different 3D functions by rotating, zooming, and changing the equation.
