5a:T47d,For alle vinkler $v$ gjelder $\sin^2 v + \cos^2 v = 1$. Dette følger fra Pytagoras: $(\cos v)^2 + (\sin v)^2 = 1^2$ på enhetssirkelen. Nyttig for å finne $\sin v$ når $\cos v$ er kjent (og omvendt).

5b:T4c1,Enhetssirkelen har sentrum i origo og radius $1$. For en vinkel $v$ fra positiv $x$-akse er: $\cos v$ = $x$-koordinaten til punktet på sirkelen $\sin v$ = $y$-koordinaten til punktet på sirkelen Dette utvider definisjonene til alle vinkler, ikke bare $0° < v < 90°$.
