Frequently Asked Questions

What is the unit circle?

The unit circle is a circle with radius 1 centered at the origin (0,0) in the coordinate plane. It's used to define trigonometric functions for all angles.

How do I find sin, cos, and tan values?

For any angle θ, the point (cos θ, sin θ) lies on the unit circle. Tan θ = sin θ / cos θ. The calculator shows these values for any angle.

What are radians and degrees?

Degrees and radians are units for measuring angles. 360° = 2π radians. The calculator can work with both units and convert between them.
