I get that × must be a variable, not an operator. It is still wide open to interpretation though. It is impossible to tell where the arguments of the trigonometric functions begin and end. Parentheses would be helpful. And what is it with those two consecutive cosine functions (cos cos)? Is one of them in the argument of the other?
