Q. Given the following point on the unit circle, find the angle, to the nearest tenth of a degree (if necessary), of the terminal side through that point, 0∘≤θ<360∘.P=(0,1)Answer:
Determine Position Angle θ: Determine the standard position of the angle θ whose terminal side passes through the point P=(0,1) on the unit circle. The point (0,1) corresponds to the top of the unit circle where the y-coordinate is 1 and the x-coordinate is 0. This is the point where the unit circle intersects the positive y-axis.
Recall Angle Measurement: Recall that the angle in standard position whose terminal side intersects the positive y-axis is 90 degrees or 2π radians. This is because the angle is measured from the positive x-axis, and a quarter turn counter-clockwise (which is the positive direction for angles) places the terminal side on the positive y-axis.
Exact Angle Calculation: Since the point (0,1) is exactly at the top of the unit circle, we do not need to approximate the angle; it is exactly 90 degrees. There is no need for further calculation or approximation to the nearest tenth of a degree.
