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 ti84 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
