I'd likely not have issue with the second derivitive if I could figure the first.
the xy is easy, just product rule. the other side, however, I'm not sure how to get dy/dx. Is it simply dy/dx ye^x - d/dx xe^y and then you can just use the product rule? If someone can work that out, I can figure out what you did.
also:
y=3e^(x^(2-1))*x^(x-1) find y'. I can even begin to describe where I get lost there.
and:
lim x->0 (e^-x-1)/(1-e^x)
I can do these with non e^x but these are the only ones that are throwing me off. Thanks for any help!
