Question: How to ask Maple not to calculate the integral but just display it


I am asking the students to write down the integral  (1/3)*int(10*cos(2*Pi*t/3),t=-1..1) without calculating it.  Both Maple TA in student answer, and Maple in my algorithm evaluate the integral. I just want the formula to be displayed not evaluated. How can I do that.  Thanks in advance.
