I want to buy second-hand textbooks but I was wondering whether it mattered if the ISBN was different from the ones on the textbooks sold at connect books. Would everything in the textbook still be the same?
Question:
Show that the maximum value of <a href="http://www.codecogs.com/eqnedit.php?latex=\frac{\ln x}{x}" target="_blank"><img src="http://latex.codecogs.com/gif.latex?\frac{\ln x}{x}" title="\frac{\ln x}{x}" /></a> is <a href="http://www.codecogs.com/eqnedit.php?latex=\frac{1}{e}"...
actually i wrote the question wrong
it's actually 3-2(cos(x^2))x - 3sinx =0
and i got it mixed up with 2sin(^2)x + cos x -2 = 0
mind doing both of them? both are between 0 and 360 degrees
i) a=-4, d=-8
Sn = (100/2)[2(-4)+(100-1)(-8)]
S100 = -40 000
ii) -40 000 -8 = -40 008
And the rest? lol
i couldn't be bothered then. but i've done it now. check the post again. i edited it.
