Question

Im trying to find the derivative.
z^(1/2)*e^(-z)
Its in the chain rule section
Answer is e^(-z)/2z^(1/2)-ze^(1/2-z)

Answer 1

u gotta use product rule as well

Answer 2

ok that makes sense

Answer 3

\[\frac{d\sqrt{z}e^{-z}}{dz}=\frac{d\sqrt{z}}{dz}e^{-z}+\frac{de^{-z}}{dz}\sqrt{z}\]
\[\frac{de^{-z}}{dz}=\frac{de^{-z}}{d(-z)}\frac{d(-z)}{dz} \]
