Answer:
[tex]\left(+\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2}\right)[/tex]Explanation:
Given the angle:
[tex]-45\degree[/tex]First, determine the equivalent angle on the unit circle:
[tex]-45\degree=360\degree-45\degree=315\degree[/tex]Thus, the coordinates of the point on the unit circle for the angle 315 degrees is:
[tex]\left(+\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2}\right)[/tex]
