Problem
The angle $\theta$ is an integer (e.g. $0, \pm 1, \pm 2, \ldots$ ) when measured in radians. Give the radian measure of the angle. (It helps to remember $\pi \approx 3$.) The radian measure of the angle is 0
Solution
Step 1 ：The angle $\theta$ is an integer (e.g. $0, \pm 1, \pm 2, \ldots$ ) when measured in radians. Give the radian measure of the angle. (It helps to remember $\pi \approx 3$).
Step 2 ：The radian measure of the angle is 0
Step 3 ：Final Answer: The radian measure of the angle is \(\boxed{0}\)
