Hello,
quick question really.
Find the area bound by the x axis, [itex]x = 1[/itex], [itex]x = 4[/itex] and [itex]y = 2/x[/itex]
Representing this graphically, the question is equivalent to performing the definite integral of [itex]y = 2/x[/itex] from [itex]1[/itex] to [itex]4[/itex]. Right?
Which would result in the area being equal to [itex]2 ln(4)[/itex]
It seems painfully obvious but this question has made me doubt myself so I wanted to check I haven't missed anything obvious... i.e is there any reason to do the longhand of subtracting the smaller areas from the larger ones.
Thanks,
BOAS
