Hey Mechano and welcome to the forums.

Looks good to me with the chain rule and proper substitution but its been a while since I've done any vector calculus or line integrals, but based on the identities, the chain rule and the substitution looks good.

Hopefully we can get a few more clarifications here just to be sure.
 


I'm grateful your quick response Chiro, I"m agree with you, let's waiting the other clarification to be sure of solution's validity
 


for the same problem above, can you help me to suggest solution to find

\ointgdf
 


would you please check the attachment, I solved above question and I need your approval
