Q10. find the area between the curve y=ln x, the y-axis and the lines y=2 and y=4, 3 sgn.fig.
ans: 47.2 units^2

thx

very simple... your area is bounded by the y axis so you should consider integrating the curve with respect to y... i.e. since y=ln x, x=e^y

So just find

lol thx I did e^y before but I integrate with ln instead of without ln. anyways I got the answer XD ha silly mistake
