Click For Summary
The area of the region in the first quadrant bounded by the lines y=x, x=2, and the curve y=1/x² is calculated using the integral from 1 to 2 of (x - 1/x²). The integral evaluates to 1, confirming the area is indeed 1. The calculations involve finding the antiderivative and applying the limits correctly. The discussion confirms the method and the result as accurate. The area between the curves is thus established as 1.

Find the area of the region in the first quadrant
bounded by the line $y=x$, the line $x=2$, the curve $y=\frac{1}{x^2}$

$$\int_{1}^{2}\left(x-\frac{1}{{x}^{2}}\right) \,dx$$
just seeing if this is the way to go.

Looks good to me!
 
The rest was easy the Area $ = 1$
 
Let's just see about that...

$$\int_1^2\left(x-\frac{1}{{x}^{2}}\right)\,dx=\left[\frac{x^2}{2}+\frac{1}{x}\right]_1^2=\left(2+\frac{1}{2}\right)-\left(\frac{1}{2}+1\right)=1$$

Yep...you are correct. (Mmm)
