Answer:

31.

Step-by-step explanation:

5+5 = 10 + 1 = 11

12 + 12 = 24 +1 = 25

15 + 15 = 30 + 1 = 31

I don't know I tried to see if that was the pattern. It checks out math wise.

EXAMPLE 5 Evaluate the iterated integral 5 0 5 x sin(y2) dy dx. SOLUTION If we try to evaluate the integral as it stands, we are

Dimas [21]

$\displaystyle\int_0^5\int_x^5\sin(y^2)\,\mathrm dy\,\mathrm dx$

The integration region is the triangle in the $x,y$ plane bounded by the lines $y=5$ , $y=x$ , and $x=0$ . Reversing the order of integration, this is equal to

$\displaystyle\int_0^5\int_0^y\sin(y^2)\,\mathrm dx\,\mathrm dy=\int_0^5y\sin(y^2)\,\mathrm dy$

For the remaining integral, let $u=y^2\implies\mathrm du=2y\,\mathrm dy$ :

$\displaystyle\int_0^5y\sin(y^2)\,\mathrm dy=\frac12\int_0^{25}\sin u\,\mathrm du=-\frac12\cos u\bigg|_0^{25}=\frac{1-\cos(25)}2$
