Answer:

The terminal point is (1, 0) D

Explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis

  • The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0 or 2π radians and cosФ = 1, sinФ = 0
  • The terminal point on the positive part of the y-axis is (0, 1),which means Ф =
    (\pi )/(2) radians and cosФ = 0, sinФ = 1
  • The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = π radians and cosФ = -1, sinФ = 0
  • The terminal point on the negative part of the y-axis is (0, -1),which means Ф =
    (3\pi )/(2) radians and cosФ = 0, sinФ = -1

In a unit circle

Ф = 2π radians

→ By using the 1st rule above

The terminal point is (1, 0)
