if the sin 0° = 0, then which statement is true? (6 points)
o
cos 90º = 1, because the cosine and sine are complements
cos 180°
1, because the cosine and sine are supplements
cos 90º = 0, because the cosine and sine are complements
o
cos 180º = 0, because the cosine and sine are supplements

, because the cosine and sine are complements

Step-by-step explanation:

Sine and cosine are trigonometric complementary functions. If we are talking about a right triangle we will have the following:

(1)

(2)

Let's prove it:

(3)

(6)

cos 90° = 0, because the angles are complements

Step-by-step explanation:

cos 90° = 0

sin 0° = 0

sin and cos are complementary

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
