Homework Statement
Evaluate
[tex]\oint x^2 (1-x^3)^6 dx[/tex]
Homework Equations
The Attempt at a Solution
let u= 1-x^3
du= -3x^2
-1/3 du= x^2 dx
-1/3 [tex]\oint (u)^6 [/tex]
= -1/3 (u^7/7)
= -1/21 (1-x^3)^7 + C
Is this done correct? I think I followed all the right steps but there is something about it that has me wondering.
