English: A unit circle with sine (sin), cosine (cos), tangent (tan), cotangent (cot), versine (versin), coversine (cvs), exsecant (exsec), excosecant (excsc) and (indirectly) also secant (sec), cosecant (csc) as well as chord (crd) and arc labeled as trigonometric functions of angle theta. It is designed as alternative construction to "Circle-trig6.svg" possibly making some relations between the functions more obvious (and others less obvious). The file deliberately uses the same style and naming conventions as "Circle-trig6.svg". It was derivated from "Circle-trig6.svg" but completely reworked.
