Question

Enter the coordinates of thepoint on the unit circle at thegiven angle.-45°

Answer 1

Answer:

$\left(+\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2}\right)$

Explanation:

Given the angle:

$-45\degree$

First, determine the equivalent angle on the unit circle:

$-45\degree=360\degree-45\degree=315\degree$

Thus, the coordinates of the point on the unit circle for the angle 315 degrees is:

$\left(+\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2}\right)$
