The notation tan-1 may mean two different things in math: tan-1(x) = 1/tan(x) = cot(x), i.e., we deal here with the multiplicative inverse; or tan-1(x) = arctan(x), so the inverse function of the tangent.We're answering here the question of what is the angle whose tangent is equal to x.; People who write tan-1 most often have in mind the latter meaning: why would you bother …
