Answer

$-\sin{t}$; $-\csc{t}$; $-\tan{t}$; odd

Work Step by Step

RECALL: (1) $\sin{(-a)} =-\sin{a}$ (2) $\csc{(-a)} = -\csc{a}$ (3) $\tan{(-a)} = -\tan{a}$ (4) A function $f$ is odd if $f(-x) = -f(x)$. Thus, using the rules listed above, the missing expressions in the given statements are ( in order) : $-\sin{t}$; $-\csc{t}$; $-\tan{t}$; odd
