Answer 1

On the unit circle, the cosine of an angle θ corresponds to the x-coordinate of a point on the circle.

1. The largest value of cosine of \( \theta \) is \( 1 \), which occurs at \( \theta = 0 \) radians (or any multiple of \( 2\pi \)).
2. The smallest value of cosine of \( \theta \) is \( -1 \), which occurs at \( \theta = \pi \) radians (or any odd multiple of \( \pi \)).

So the answers are:
- The largest value of cosine of \( \theta \) is **1**.
- The smallest value of cosine of \( \theta \) is **-1**.
