Consider the following.

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}\frac{\sqrt[\phantom{2}]{81-x^2}}{x}dx$

Find the indefinite integral using the substitution $x=9sin().($Remember to use absolute values where appropriate. Remember the constant of integration.$)$

$[-/8$ Points$]$

LARCALC$128\mathrm{.}4\mathrm{.}007.$

Find the indefinite integral using the substitution $x=3sec().($Remember to use absolute values where appropriate. Remember the constant of integration.$)$

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}\frac{1}{\sqrt[\phantom{2}]{x^2-9}}dx$
