# Definite Integral

##### New member
My professor sent out an online work sheet with tons of practice problems, and I'm having trouble with this one, is my answer right? (see link) I chose this because a definite integral has to have limits, correct?

Re: Calculus Definite Integral help?

Hi there pleashelpme,

Yep, you are correct. A definite integral must have limits of integration, or bounds. By the way, this is just a practice assignment right? We as a rule can't directly give or confirm answers for graded assignments unless the professor is ok with it.
