Perl has sin and cos, but no tan. I know you can make your own tan function, but that's not the point. It's not convenient (hence, unPerlish) for the programmer to make his/her own (or load a module to do so). Besides, calling sub in Perl is expensive. Even many calculators have a button for the tan function.
