I have a Casio fx-991, and it calculates the values of definite integrals very accurately. I can assure you 150%, the answer is 11/12 pie.

Hahaha, nah trust it. I've been using it all throughout the semester on past paper questions that involve definite integrals and they all come out correctly.

You will lose 1 mark as an Error Carried Forward in my opinion.
