I have tried that several times but keep coming up with the wrong answer.Char. Limit said:Well, there is usually a factorial button in your calculator, somewhere.
Try under the MATH menu.
Yep, I see the factorial button.Char. Limit said:Well, there is usually a factorial button in your calculator, somewhere.

Yes I'm sure.Char. Limit said:Well, your formula should be correct. Are you sure your x and \lambda values are correct?
