Question

(a) If we mark off a distance t along the unit circle, starting at (1, 0) and moving in a counterclockwise direction, we arrive at the --Select--- point determined by t. (b) What are the terminal points determined by $\pi$/2, $\pi$, -$\pi$/2, and 2$\pi$? $\pi$/2 (x, y) = $\pi$ (x, y) = -$\pi$/2 (x, y) = 2$\pi$ (x, y) =

Step 1

The unit circle is a circle with a radius of 1, centered at the origin (0,0) of the coordinate plane. Angles in the unit circle are measured in radians, and we start measuring from the positive x-axis (1,0) in a counterclockwise direction. Show more…
