Enter The Coordinates Of Thepoint On The Unit Circle At Thegiven Angle45 class=

Sagot :

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]
