SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Find the terminal point
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-axis.
Rule 1: 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
Rule 2: The terminal point on the positive part of the y-axis is (0, 1),which means Ф = radians and cosФ = 0, sinФ = 1
Rule 3: The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = π radians and cosФ = -1, sinФ = 0
Rule 4: The terminal point on the negative part of the y-axis is (0, -1),which means Ф = radians and cosФ = 0, sinФ = -1
In a unit circle, Ф = π radians. By using the 2nd rule above,
The terminal point is:
