Question

An angle in standard position measures radians, and P(0, 1) is on the terminal side of the angle. What is the value of the cosine of this angle?
–1
0
1
undefined

Answer 1

Answer: 0

Explanation:

1) Cosine trigonometric ratio definition:

cos (α) = adjacent-leg / hypotenuse

2) P (0,1) ⇒ 

- adyacent-leg = x-coordinate = 0
- opposite-leg = y-coordinate = 1
- hypotenuse = √[x² + y² ] = 1

3) Therefore, cos(α) = 0 / 1 = 0
