Hello, I am trying to do a definite integral on my TI89Titanium and when I try to integrate using any sort of trigonometric function, i get an error. Other simple functions of x work very well and easily, but I could do those by hand. Anyone know anything?

Error example: "Non real result"

Which the result was pi, after either solving by hand or wolfram alpha, and that is also consistant with the textbook.

Or, "too few arguments"

Thanks to anyone who can help. I bought this calculator thinking it would make exams easier and quicker, but I am spending more time how to learn how to use damn thing than anything.
