Hello,
Can you check if they really used the log in the integral and the ln in the answer ? That's pretty weird.
Oops. That last flub was an error on my part. You're right. This is my work, in case you thought I copied this from an answer book.
All I have down for an answer is (ln2)^2. I don't have a solutions manual. Either way, that answer minus my last error, is not equal. Is my work correct aside from that?
Another solution manual error?
Oh I thought the result was from a book. (I must say, it's really good that you show your working )
The problem in that is I don't know what log stands for, because it depends on the books !
So, assuming that this "log" is base 10, the answer is
If this "log" is the napierian (natural) logarithm, then the answer is simply
Your work is correct aside that. There's just the confusion log / ln that just affects the result.
