Short Answer

Expert verified

The required solution is 2.

Step by step solution

Definition of double integral

The double integral of f(x,y) over the area Ain the (x,y) plane as the limit of this sum, and we write it as $\int \int_{A} f (x, y) dxdy$

Drawing the area bounded by the curve

The area of integration or bounded region is shown below,.

Calculation of the area under the curve changing boundaries

Changing the boundaries of the given integration:

$x : 0 \to ττ, a and y : 0 \to x$

So, the integration

$l = \int_{0}^{π} \frac{\sin x}{x} dx \int_{0}^{x} dy = \int_{0}^{π} \frac{\sin x}{x} x = \int_{0}^{π} sinxdx = {- \cos x}_{0}^{π} = 2$

Therefore, the integration value is, 2.
