Step-by-step explanation:
we know that
In the unit circle
The coordinates of a point have the following rule
where
(x,y) are the coordinates of the point a r is the radius
but remember that in a unit circle the radius is equal to 1
so
<em><u>Find the x-coordinate of each case</u></em>
Part 1) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
Part 2) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
Part 3) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
Part 4) we have the point
so
The y-coordinate is
Find the value of the x-coordinate
substitute
