Problem 2502

d) Using the substitution from c ), write $Q$ in terms of $x$ using the appropriate inverse trig function.
FORMATTING: Pay attention to Móbius syntax for inverse trig functions/ e $\mathrm{g} \mathrm{sin}^{-1}(\mathrm{a})$ is wriften as arcsin(a). $\sec ^{-1}(a)$ is written as arcsec(a), and $\tan ^{-1}(a)$ is written as $\arctan (a)$ , etc. $Q=$ e) Using the substitution from c), write each trig ratio in terms of $x$ .
Hint: You might find it helpful to draw a right triangle with acule angle $Q$ and sides based on your substitution from c). FORMATIING: Write $\sqrt{a}$ as sqrt(a) and use calculator notation. Your answers should not involve trig functions nor the variable $Q$ . $\begin{array}{lll} \sin (Q)=\square & \csc (Q)=\square \\ \cos (Q)=\square & \sec (Q)=\square \\ \tan (Q)=\square & \cot (Q)=\square \end{array}$ 固 블 $\square$ f) To complete this trig substitution, find $\frac{\mathrm{d} x}{\mathrm{~d} Q}=\square$ so that you can substitute $\mathrm{d} x$ from the original integral with dx $=$ $\square$ FORMATIING: Do not include $\mathrm{d} Q$ in your answer, it is aiready writien for you g) Next, use the work you've done and apply the substitution for $z$ and $\mathrm{d} z$ . Then, use the right side of your cleverly-chosen trig identity to eliminate the square root and simplify the integrand. This should transtorm the original integral, wricten in terms of $x$ , into a new integral in terms of $Q$ which does not contain any square roots! $\int \frac{x^{3}}{\sqrt{x^{2}+36}} \mathrm{~d} x=\int g(Q) \mathrm{d} Q$ $\square$ The new integrand is $g(Q)=$ 준 FORMATTING: Your answer for g( $Q$ ) should not include any radicals ( $i$ e. do not use sqri()). it should not include absolute value (i.e. do not use abs()). It may be a mathernatical expression involving trig functions and the variable $Q$ . Pay attention to Möbius syntar for powers of trig functions, e.g. sin ${ }^{2}(a)$ must be written as $(\sin (a))^{\wedge} 2$ .
