Chapter 5: Q17P (page 247)

$鈭� (\frac{x}{y})$ over the triangle with vertices $(0, 0), (1, 1), (1, 2)$

Short Answer

Expert verified

The required solution is $\frac{I n 2}{2}$ .

Step by step solution

Step 1: Definition of double integral

The double integral of $f (x, y)$ over the areain the $(x, y)$ plane as the limit of this sum, and we write it as ${鈭�}_{A} f (x, y) d x d y$ .

Drawing the area bounded by the curve

The area is bounded by the triangle with vertices $(0, 0), (1, 1), (1, 2)$ ..

Calculation of the area under the curve

Integrating over the variable y

${鈭�}_{A} \frac{x}{y} d x d y = {鈭�}_{x = 0}^{1} [{鈭�}_{x}^{2 x} \frac{d y}{y}] x d x = {鈭�}_{0}^{1} (I {n y}_{x}^{2 x}) x d x = {鈭�}_{0}^{1} (I n (2 x) - I n x) x d x$

Further calculation

Integrating over the variable x

${鈭�}_{0}^{1} (I n (2 x) - I n x) x d x = {鈭�}_{0}^{1} (I n 2 + I n x - I n x) x d x = {\frac{I n 2}{2} x^{2}}_{0}^{1} = \frac{I n 2}{2}$

Therefore, the value is $\frac{I n 2}{2}$
