EGK Calculus AR is a revolutionary educational app that brings calculus concepts to life using immersive Augmented Reality (AR). Whether you're a high school student, university learner, or just a curious mind, this app helps you deeply understand core ideas like limits, derivatives, and integrals through interactive, visual learning. Say goodbye to flat textbook diagrams and hello to dynamic, 3D visualizations you can walk around, observe from different angles, and interact with in real-time. Watch how a sine curve forms, see how a derivative changes slope, or visualize the area under a curve—all from your phone or tablet. Key Features: AR Graph Plotting: Instantly plot mathematical functions like sine, cosine, and polynomials in your physical environment. Limit Visualization: Understand how functions behave as x approaches a value, with clear left/right-hand visual cues. Derivative Tool: Tap a point to see the slope of the tangent line calculated and displayed in AR. Integral Area Visualization: (Coming Soon) See the area under a curve build dynamically using methods like the trapezoidal rule. Interactive Quizzes: Reinforce your learning with multiple-choice questions after each concept. Tactile Gestures: Rotate and move graphs in AR space with intuitive gestures for full spatial understanding. Math Input Engine: Type functions in familiar notation (e.g., sin(x), x^2 + 3x) and watch them render instantly. Beginner Friendly: No prior calculus experience needed—ideal for students just starting out. Modern SwiftUI + RealityKit Interface: A polished, smooth, and engaging user interface built for iOS devices. Educational Impact: EGK Calculus AR turns abstract math into something visual, interactive, and memorable. Students no longer have to imagine what a derivative looks like—it’s right in front of them, in 3D. Ideal for use in classrooms, study sessions, or solo exploration. Requirements: iPhone or iPad with ARKit support (iOS 15 or later) Stable lighting and a flat surface for best AR tracking Why EGK Calculus AR? Because math is better seen than just read. And with AR, your environment becomes a living textbook.
