Question 1

Diberikan integral lipat $\displaystyle \iint_D (\var{a^2}-x^2-y^2)\, dA$ .

Daerah $D$ agar hasil integralnya negatif adalah $\ldots$ .

$\{(x,y)\mid -\var{a}\leq x\leq \var{a},\, -\var{a}\leq y\leq \var{a}\}$
$\{(x,y)\mid 0\leq x\leq \var{a/2},\, -\var{a/2}\leq y\leq 0\}$
$\{(x,y)\mid -\var{2*a}\leq x\leq -\var{a},\, \var{a}\leq y\leq \var{2*a}\}$
$\{(x,y)\mid -\var{a/2}\leq x\leq 0,\, 0\leq y\leq \var{a/2}\}$

Expected answer:

$\{(x,y)\mid -\var{a}\leq x\leq \var{a},\, -\var{a}\leq y\leq \var{a}\}$
$\{(x,y)\mid 0\leq x\leq \var{a/2},\, -\var{a/2}\leq y\leq 0\}$
$\{(x,y)\mid -\var{2*a}\leq x\leq -\var{a},\, \var{a}\leq y\leq \var{2*a}\}$
$\{(x,y)\mid -\var{a/2}\leq x\leq 0,\, 0\leq y\leq \var{a/2}\}$
