Nilai sinus sudut istimewa

\sin 0^o = 0\,

\sin 15^o = \frac {\sqrt{6} - \sqrt{2}}{4}\,

\sin 30^o = \frac{1}{2}\,

\sin 37^o = \frac{3}{5}\,

\sin 45^o = \frac {\sqrt{2}}{2}\,

\sin 53^o = \frac{4}{5}\,

\sin 60^o = \frac {\sqrt{3}}{2}\,

\sin 75^o = \frac {\sqrt{6} + \sqrt{2}}{4}\,

\sin 90^o = 1\,
