Question

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

Answer 1

`\left(+(√(2))/(2),-(√(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(+(√(2))/(2),-(√(2))/(2)\right)`
