(multiple possible answers) $-5.28$ radians $7.28$ radians $13.56$ radians
RECALL: (i) The angles cotermnal with $\theta$ can be found using the formula $\theta_1=\theta + 2n\pi$, where $n$ is an integer (ii) $\pi \approx 3.14$ Thus, using the formula in (i) above and using $\pi=3.14$, three angles that are coterminal with $1$ radian are: (1) $1+2(1)(3.14) = 1+6.28=7.28$ (2) $1+2(-1)(3.14) = 1-6.28= -5.28$ (3) $1+2(2)(3.14) = 1+12.56=13.56$
