Quiz: calculating a definite integral

[Namir]

I do believe the program should be:

Code:

01 LBL 0
02 ENTER
03 CHS
04 yx
05 RTN

For the built-in integral to work! your answer is correct!

Now to answer your question. I would use an open Newton-Cote numerical integration method since this class of methods do not evaluate the integral at the end points, just in case my machine barks at evaluating 1/0^0.
