What is the Unit Circle Calculator?

The Unit Circle Calculator is an interactive tool that helps students, teachers, and math learners visualize angles, trigonometric values, and unit circle coordinates with complete clarity. By entering or adjusting the angle, the calculator instantly shows cosine, sine, tangent, and other trig ratios, along with a live graphical point on the unit circle. This allows you to explore how angles behave, understand radian–degree conversion, and learn trigonometry through an intuitive visual experience.

How to Use:

1. Enter Angle: Type the angle in degrees or radians.
2. Choose Unit: Select whether the angle is in degrees or radians.
3. Use the Slider: Drag the slider to change the angle smoothly.
4. Click the Buttons: Convert to radians or view the unit vector for the given angle.
5. Click on the Circle: Tap anywhere on the circle to set the angle visually.
6. Review Calculations: The tool displays cos(θ), sin(θ), tan(θ), sec(θ), csc(θ), and cot(θ), along with a graphical point and tangent line for better understanding.
