Step-by-step explanation:
We want to find the coordinates for the point on the unit circle at;
![\theta=(3)/(2)\pi=270^(\circ)](https://img.qammunity.org/2023/formulas/mathematics/college/fgam3t601d7zo7ugyb9c209mtl0dmaf141.png)
The coordinates of a point on the unit circle at 270 degree would be;
Therefore, the coordinates of a point on the unit circle at 270 degree is;
![(0,-1)](https://img.qammunity.org/2023/formulas/mathematics/college/70je86pfd1336z0vehwd9zuojqsduiu56j.png)
