TRIGONOMETRY EXPLORER

Unit Circle: Shows how sine (vertical) and cosine (horizontal) relate to circular motion.

Right Triangle: Displays the triangle formed inside the circle with labeled sides.

Waveforms: Traces sine and cosine waves over time as the angle rotates.

Exact Values: Shows symbolic forms (like √2/2, π/4) at special angles.

Fourier Builder: Demonstrates how complex waveforms are built from sine waves.

Synthesizer: Hear the relationship between frequency and pitch.

Export PNG: Save the current visualization as an image.

All controls are keyboard accessible. Use Tab to navigate between buttons and controls.

Sliders can be adjusted with arrow keys when focused.

Animation can be paused for detailed study of any position.

Values panel shows live numeric readouts of all trigonometric functions.

If your system has reduced motion enabled, the animation starts paused.

All buttons have visible focus indicators for keyboard navigation.
