6. Find the angle based on the cosine. You can use the arccos or cos-1 function on your calculator to find the angle Î¸ from a known cosÎ¸ value. For some results, you may be able to work out the angle based on the unit circle. 1  In our example, cosÎ¸ = â2 / 2. Enter arccos(â2 / 2) in your calculator to get the angle..
