## Problem 4

Convert the integral

\[
\int_0^{\sqrt{6}} \int_{-x}^x dy dx
\]

to polar coordinates and evaluate it (use \( t \) for \( \theta \)):

With \( a = \) _____, \( b = \) _____, \( c = \) _____, and \( d = \) _____, 

\[
\int_0^{\sqrt{6}} \int_{-x}^x dy dx = \int_a^b \int_c^d dr dt
\]

\[
\hspace{1em} = \int_a^b \hspace{1em} dt
\]

\[
\hspace{1em} = \left[ \hspace{10em} \right]_a^b
\]

\[
\hspace{1em} = \hspace{10em}.
\]

### Explanation

The problem involves converting a given double integral from Cartesian coordinates to polar coordinates and then evaluating it. 

In Cartesian coordinates, the limits of integration are from \( y = -x \) to \( y = x \) and from \( x = 0 \) to \( x = \sqrt{6} \). The task is to find the corresponding limits in polar coordinates (\( r \) and \( \theta \)) and then rewrite and evaluate the integral.

The integral bounds for \( r \) and \( \theta \) need to be determined and will be substituted into the integral in the polar form.

The step-by-step process is indicated in sections where values \( a \), \( b \), \( c \), and \( d \), and the resulting substitutions, need to be filled in and calculated.
