Hi, I'm very confused about these:
1. y=2^ln x
for #1, wouldn't it be:
y'=ln x (2^ln x) (ln 1/x) ?
but the answer in the book says it's y'=ln x (2^ln x) (1/x).
and I have absolutely no idea how to begin #2.
sorry, but these too:
3. f(x) = Ae^-Bx
book says f'(x) = Ae^-Bx (-B). I don't understand where would the -Bx go
4. f(x) = L/(1+Ae^-Bx)
thank you so much in advance!
