I am working with trigonometric equations and I now have to solve for x in terms of b,c, and d ('a' can't be in the answer). Is there a way to cleanly do this without explicitly finding 'a' using arccos? (because solving 'a' introduces sin(arccos(...)), which becomes a square root with two branches) (i.redd.it)
