      It's not an identity per se because if it were then the argument would be in terms of a variable. Another thing I find interesting about the statement is that we have inverse trig functions. The math statement is true and can be verified with a calculator. An identity is a math sentence that states that it's true for ALL values of a variable except when there's excluded values. The statement can be verified as true.
