Evaluate the definite integral by expressing it in terms of $u$ and evaluating the resulting integral using a formula from geometry.

$\int_{e^{-3}}^{e^{3}} \frac{\sqrt{9-(l n)^{2}}}{x} d x ; \quad u=\ln x$

Equation Transcription:

$u$

$\int\limits_{{e}^{-3}}^{{e}^{3}}\ \ \frac{\sqrt{9\ -\ (ln{)}^{2}}}{x}\ dx;\ \ \ u\ =\ ln\ x$

Text Transcription:

int_{e^ -3}^{e^3} frac{sqrt{9 - (ln)^2} {x} dx ; u = ln x
