Question
The area of the region enclosed by the curves $y=x$, $x=e, y=\frac{1}{x}$ and the positive $X$ -axis is(a) 1 sq unit(b) $\frac{3}{2}$ sq units(c) $\frac{5}{2}$ sq units(d) $\frac{1}{2}$ sq unit
Step 1
Setting $x=\frac{1}{x}$, we get $x^2=1$, which gives $x=1$ and $x=-1$. Since we are only interested in the positive $x$-axis, we consider $x=1$. Show more…
