All function names must be given in lower-case letters. The trigonometric functions require that their arguments be given in radians. Conversely, the inverse trigonometric functions give their results in radians.
You should note that the functions require that their arguments be enclosed in parentheses, but that the arguments do not have to be simple numbers. You may have a complicated expression as the argument for a function, and you may even nest the functions, using one function (or an expression including one or more functions) as the argument for another.
