Integration -- basic problems
I don't think I really understand what I am doing. This topic has me a little befuddled, so please bear with me.
First, how do you correctly express the integration of a constant? (And no, my text does not explain this. I have looked several times.)
I understand that the answer is 10 (the area bound by the lines and ) but not how to obtain or express that answer using the definite integral.
Does not seem to make sense when f(x) is a constant.
Thanks for the help! Integration may be my waterloo.
