    I just need to know if I did it right


    3. The attempt at a solution
    I got (5pi/6)-1/9

    You are much more likely to get a reply if you explain how you got that result.

    My thoughts exactly. To check this work, we have to do the integration for ourselves, which is a lot more work than if we can see what you (pmqable) did.
