About 2D Trigonometric Circle
🧠Description – 2D Trigonometric Circle
Learn trigonometry and harmonic motion in a practical and visual way!
The 2D Trigonometric Circle is an educational app designed to help students and teachers understand sine, cosine, angles, and periodic oscillations in an intuitive manner.
With a simple and modern interface, you can move the point on the circle and visualize the variation of sine and cosine values in real-time, displayed in both degrees and radians. The application now also includes an interactive simple pendulum experiment, allowing you to observe how oscillatory motion is directly related to trigonometric functions.
🎯 Key Features:
Simultaneous visualization of degrees and radians.
Dynamic display of sine and cosine values.
Interactive simulation of the simple pendulum.
Responsive and user-friendly interface.
Ideal for high school students and Adult Education (EJA/GED-prep).
Useful tool for Math and Physics teachers.
🧠Learn by playing: See how every angle and movement relates to trigonometric ratios and practically understand the fundamentals of the pendulum and Simple Harmonic Motion (SHM).
👨‍🏫 Developed by a teacher, designed for clear and practical learning.
