(choose chapter or problem)

Evaluate the integral by making an appropriate change of variables.

$\iint_{R} \sin \left(9 x^{2}+4 y^{2}\right) d A$, where $R$ is the region in the first quadrant bounded by the ellipse $9 x^{2}+4 y^{2}=1$

Equation Transcription:

$\int\limits_{\ }^{\ }\int\limits_{R}^{\ }sin(\ {9x}^{2\ }\ +\ {4y}^{2})\ dA\ \$

$R$

${{9x}^{2}\ +\ {4y}^{2}\ =\ 1}^{\ }$

Text Transcription:

double integral_R sin(9x^2 + 4y^2) dA

9x^{2} + 4y^{2} = 1
