Question #59cfa Trigonometry Inverse Trigonometric Functions Basic Inverse Trigonometric Functions 1 Answer Monzur R. Feb 4, 2017 2/3pi Explanation: The tan() and tan^-1() functions are like inverses of each other, so if we apply them both at the same time, they cancel out. It's a bit like multiplying and dividing by the same number; we're left with what we started with. Answer link Related questions What are the Basic Inverse Trigonometric Functions?
