Question

Hi,
I have to teach a math class on Monday for my adviser and he gave me some of Pauls online notes. On the link below, Average function Value example b). Is there a mistake here?
The example says: integral of sin(2z)*exp(1-cos(2z)). The solution given is: exp(1-cos(2z)). I think there is a factor of 1/2 missing or am I missing something? The link to the document is here:
