How To Calculate Derivatives On My Fx-991es?

I've got a new fx-991Es casio calculator. I just can't find out how can I calculate a derivative on my calc.
For example: I need to know what a derivative of x^3. I'm pressing on SHIFT then button with derivative image and then I get a derivative sign on display with 2 parameters to enter. The first one in the brackets is a function that I want to calculate, I suppose. So I type there x^3, I press on ALPHA then red X, SHIFT and ^3. But I can't understant what the second parameter is? And what I have to type there... If I type there nothing I got an error.
Please advice!
