Use a calculator to solve csc (theta) = -3. I know the answer is 3.48 and 5.94 but I need the steps to take on the calculator to arrive at the answer. I have a ti-84 calculator. thanks!

    if csc(theta) = -3.1, sin(theta) = -1/3.1 = -0.3226

    arcsin(-0.3226) = 5.9547 radians
    The reference angle is 0.3285 radians. Add that to pi for the other angle. I get 3.47 radians, not 3.48
