good!Secondly for part b) I didnt think there were any maxima/minima because of what I said above. However, differentiating the function I get
lnx + x(1/x)
equating to zero gives
lnx + 1 = 0
lnx = -1
lnx = -lne
lnx = lne^-1
x = 1/e
yup. you're a genius!Plugging this into the second derivative (which is 1/x) gets me e as a minima.
Is this correct?
use integration by parts with andAnd for the last part it tells me to use integration by parts, but it doesnt get me anywhere...
you know what u and dv represent, right?
