Exercise \(\PageIndex{1}\)
Sketch the regions and evaluate the integrals:
1) \(\int_1^{\ln 8} \int_0^{\ln y} 2e^{x+y} \, dy dx\)
2) \(\int_0^{2} \int_x^{2} 3y^2 sin({xy}) \, dy dx\)
3) \(\int_0^{1} \int_0^{3} \frac{4x^2}{(y-1)^{2/3}} \, dy dx\)
4) \(\int_{-\infty}^{\infty} \int_{-\infty}^{\infty} \frac{3}{(x^2+1)(y^2+1)} \, dy dx\)
5) \(\int \int_{x^2+y^2 \leq 1} \ln (x^2+y^2)\, dA\)
6) \(\int_0^2 \int_{y/2}^1 y e^{x^3} \,dx dy\)
7) \(\int \int_Q \frac{dA}{(1+x^2)(1+y^2)}\), where \(Q\) is the first quadrant of the \(xy-\)plane.
8) \(\int \int_R x \cos (y) \,dA\), where \(R\) is the region bounded by the coordinate axes and the curve \(y=1-x^2.\)
