The reference angle is the smallest angle between the terminal side of the given angle and the x-axis. Since $6.1$ radians is more than $2\pi$ (approximately $6.28$ radians), we subtract $2\pi$ to find the equivalent angle within one full rotation, which is approximately $6.1 - 6.28 = -0.18$. The reference angle is the positive acute angle, which is approximately $0.2$ radians.
