Dear all,(adsbygoogle = window.adsbygoogle || []).push({});

Sorry for the silly integration question. I haven't done calculus in ages and my memory has got really rusty! ='(

The integral question is as follows:

[tex] \int\ (X_1-\frac{X_2}{2})^2(\frac{1}{X_2}) dX_1 [/tex]

Sorry, I could not figure out how to insert the limits on my intergral. It is from 0 to [tex]X_2[/tex].

My answer is:

= [tex] \int\ (\frac{X_1^2}{X_2}-X_1 + {\frac{X^2}{4}) dX_1 [/tex]

Which, after integrating, becomes

[tex] (\frac{X_2^2}{3}-1/2X_2^2 + X_2^2/8 ] [/tex]

In the end, I get -X2^2/24, but the answer in the book is X2^2/12. What am I doing wrong? Thanks in advance for your help!
