Can someone confirm if I did this implicit differentiation problem correctly?

Question:
Find dy/dx in x^2 + y^3 = 1

My work is attached.

If someone could confirm that I have the right answer, it would be greatly appreciated!

Edit: Actually, having looked over the problem again, I've come up with a revision to my work (mywork2.pdf).

2. The second one is correct.
