sin(θ) returns the Sine of θ
Unlike its TI-83/84 counterpart which can only be a real number, or a list thereof, the nSpire version can also be used on complex numbers, as well as a list/matrix of complex numbers.

sin( is affected by the document angle setting

On CAS calculators(CAS only or non-CAS as well?), sin(θ) can result in exact representations if θ is a value such as $\pi/3$
