Angle values
150° = 5π/6: coordinates (-√3/2, 1/2), so cos is negative and sin positive — reference angle 30°, second quadrant.
How Einheitskreis-Explorer works
- Open Einheitskreis-Explorer and review the example state before entering your own values.
- Enter or select the information needed for Einheitskreis-Explorer.
- Review the result and adjust the inputs if you want to compare another case.
Explore the unit circle: how an angle maps to sine and cosine coordinates, where the exact values come from, and how signs change by quadrant. The interactive workspace runs in your browser, so you can review the result without creating an account.
