Calculate the exact value of arccos (-1). Note that a special angle is involved, so a calculator is not necessary. (Give an exact answer. Use symbolic notation and fractions where needed. Give the angle in radians. Simplify your answer completely.) arccos 2π (-²) = √²/² 3 Determine the other angle in the interval [0, 27) when cos(0) = -1/2. 0 = How many solutions does the equation cos(0) = - = -1/have in the interval [0, 2π)? Number of Solutions: radians radians
