Unit Circle Toolkit

Applied inputs, selected marks and completed drags appear here.

Import situation code

The circle has radius 1; angles may be negative or exceed one turn. Input bounds are tool limits, not mathematical limits.
Tangent lines clipped at the frame can still represent finite values. ≈ indicates rounding; undefined points are handled separately.
Substitution checks an example rather than proving an identity. The solver supports sin, cos, tan, cot of ax+b within the documented bounds.
Session persistence depends on the host platform. Copy a situation code to keep your lookup inputs yourself.
