comment Is the skill to learn new math by reading textbook alone (no lectures) required when one becomes a PhD student?
in college, instructors always recommended students reading the section that's going to be taught before going to the lecture to increase the effectiveness of the lecture. But I often find myself spending more time reading the textbook on materials that the professor might not have covered. I'm not sure I see how reading prior going to the lecture is beneficial to a student... can you help to elaborate on that a little? Thanks

sorry, im still stuck... i know the integral of $e^x$ is $e^x$ but im not sure how to handle the $z^2$

comment How is $e^x$ related to its probability density function $\lambda e^{-\lambda x} (x>0)$?
i got it, i believe you meant to write "that the probability density function of the random variable $X$ is $\lambda e^{−λx}$ [instead of $ e^{−λx}$] when $x>0$" correct?
