Answer 1

Answer: (1,0)

Step-by-step explanation:

Answer 2

ANSWER

$a. \: \: \: ( 1,0)$
$b. \: \: \: (0,1)$

EXPLANATION

a. We want to find the coordinates on the unit circle that corresponds to an angle of 0°

In general, the points on the unit circle are given by,

$( \cos( \theta) ,\sin( \theta))$

So we substitute,

$\theta = 0 \degree$
to obtain,

$( \cos( 0\degree) ,\sin( 0\degree))$

$( 1,0)$

b. For the coordinates of the point on the unit circle that corresponds to an angle of 90º,

We substitute
$\theta = 90 \degree$
to obtain,

$( \cos( 90\degree) ,\sin( 90\degree))$

This simplifies to,

$( 0 ,1)$
