Question

sin(arccos(1/2)+arcsin(1/2))=

Answer 1

with arc anything, you can look on a unit circle, or know the circle, and the arc of anything is the degree. So what is the lowest degree when cos is 1/2. Then find the degree for arcsin(1/2), add then use the combined degrees for example if the degrees equal 60 (which they don't) and solve for sin(60), and the answer should be a fraction
